Length = 5x +4
Breadth = 4x-4
Perimeter = 2(L+B)
Perimeter :
[tex]2(5x + 4 + (4x - 4)) \\ 2(5x + 4 + 4x - 4) \\ 2(5x + 4x + 4 - 4) \\ 2(9x) = 2 \times 9x[/tex]

jontae went to brunch with his family and offered to pay the bill.The total bill was $54.19 before tax. If there is a 15% how much does he pay in taxes
Answer:
$62.32
Step-by-step explanation:
54.19 · 15/100 = 812.85/100 = 8.1285
simplify 8.1285, so it's 8.13
$54.19 + $8.13 = $62.32

Find the difference
3/4 - 1/3 =
Answer:
5/12
Step-by-step explanation:
first find lcm of 3,4 the denominator to get 12
3/4-1/3
=5/12
Answer:
5/12
Step-by-step explanation:
you need to find the largest common multiple of the denominators which comes from just multiplying 4x3 which gets you 12.then you multiply the top number by whatever you had to multiply the bottom number by to get 12. from there its 9-4 which gets you five. 5/12 can not be simplified any further
9/12-4/12=5/12
a student concluded that the solution to the equation startroot 2x+1 endroot +3=0 is x=4 do you agree? explain why or why not.
Answer:
X=4
Step-by-step explanation:
Given the equation
√2x+1 + 3= 0
Subtract 3 from both sides
√2x+1 +3 +3 = 0-3
√2x1 = -3
Square both sides
{√2x+1)² =(-3)²
2x+1 =9
2x= 9-1
2x = 8
x = 8/2
x = 4
Hence I agree that the solution is x = 4 based on the explanation above

Rendering math...While solving an equation, Wayra made some mistakes. Her solution is given below. Please help her to identify the step in which there is a mistake and also the right solution. Step 1: 13(z+6) = 4(z-3)-5z Step 2: 13z+19 = 4z-12-5z Step 3: 13z+19 = z-12 Step 4: 13z+z = -19-12 Step 5: 14z =-31 Step 6: z =-3114 Wayra has made a mistake at?
Answer:
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
Step-by-step explanation:
Given the equation solved by Wayra expressed as;
Step 1: 13(z+6) = 4(z-3)-5z
She is find the value of z from the equation;
Step 2: Open the parenthesis using the distributive property;
13(z+6) = 4(z-3)-5z
13z + 13(6) = 4z - 4(3) - 5z
13z + 78 = 4z - 12 - 5z
Step 3: Simplify
13z + 78 = 4z - 5z - 12
13z + 78 = -z -12
Step 4: Collect the like terms;
13z + z = -12 - 78
Step 5: Simplify the result
14z = -90
Step 6: Divide both sides by 14
14z/14 = -90/14
z = 6.428
According to the calculation, Wayra mage a mistahe in step 2 where she added 13 and 6 together instead of multiplying to get 78.
She also make a mistake in step 2 where he subtracted 5z from 4z to get z instead of -z
Mike can run a mile in 12 minutes. He starts at 11:30 AM. and runs 4 miles. What time does Mike finish his run at?
Answer: Mike stops running at 12:18 PM
Step-by-step explanation: We know he runs 1 mile each 12 minutes and we also knows he ran 4 miles so the equation is 12*4 or (12 times 4) which is equal to 48. We then add 38 minutes to 11:30 AM and end up at 12:18 PM.
Answer:
12:18 P.M
Step-by-step explanation:
So the first thing I did was find out the amount of time it takes Mike to run 4 miles by multiplying 12 x 4 = 48
So Mike spends 48 minutes running the 4 miles.
Now we add 48 minutes to 11:30. So since there is no such thing as 11:78 I first subtracted the 30 minutes from the 48 minutes and added that to 11:30 which gave me 12:00 pm and then I just added the reamaining18 minutes.
which in conclusion means,
Mike will finish his 4 miles at 12:18 P.M

What values for PQ and RL make the following equation true px to the power of rtwo+wx+r equals(3x+1)(3x+2)HURRY
P= 3
Q= -14
R= -5
Step-by-step explanation:
Just solve the equation on the right side, you'll get:
=3x^2 -15x +x -5
=3x^2 -14x -5
Now compare it to the equation on the left side,
The coefficient of x^2 on the left is "p", on the right that we just solved is 3.
Same for "q" which is the coefficient on the left, on the right it's -14.
And for "r" it's -5 from the equation on the right.

Step-by-step explanation:
The solution is the value of f(3) = -28.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given expression is,
f(x) = -4x^2 + 4x - 4
now, we have to find the value of f(3).
so, we have to put x = 3, in the expression.
we get,
f(x) = -4x^2 + 4x - 4
f(3) = -4* 9 + 4*3 -4
or, f(3) = -36 + 12 -4
or, f(3) = -28
Hence, The solution is the value of f(3) = -28.

What is the slope of the line that passes through the points(-1,-7) and (-2,-5)?Write your answer in simplest form
Answer:
-2
Step-by-step explanation:
slope formula= (y2-y1)/(x2-x1)
(-1,-7) is (x1,y1)
(-2,-5) is (x2,y2)
Plug in numbers into slope equation
((-5)-(-7))/((-2)-(-1)) = 2/-1
Simplify
answer= -2

find the slope of the line passing through (3,7 ) and (6,11) asap
Answer:
4/3
Step-by-step explanation:
You're going to want to use the slope formula which is attached. Using this, you'll take the second y and subtract the first y from it. In other words, 11-7, which is 4. This will be the numerator. Then, you'll take the second x and subtract the first x from it. In other words, 6-3, which is 3. This will be the denominator. The final answer is [tex]\frac{4}{3}[/tex].
A cell phone company charges $40 per month for unlimited calling and $0.20 per text message sent. If t represents the number of text messages Roxy sent last month wich expression represents the cost of her bull last month before any taxes or additional fees
Answer:
Total cost = 40 + 0.2t
Step-by-step explanation:
Given:
Fixed cost for call = $40
Each message cost = $0.20
Number of message = t
Find:
Equation of total cost
Computation:
Equation of total cost
Total cost = Fixed cost for call + (Each message cost)(Number of message)
Total cost = 40 + 0.2t
Which statement accurately describes the vector shown?
Answer:
magnitude of √61 and a direction angle equal to approximately 40°
Step-by-step explanation:
I inserted the x,y axis into a vector calculator to get the magnitude and angle :D
The magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have a vector shown in the picture.
The coordinate of the vector are:
The tail coordinate = (0, 0)
The head coordinate = (6, 5)
We can find the magnitude of the vector using the distance formula:
The distance formula can be given as:
[tex]\rm M=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm M=\sqrt{(6-0)^2+(5-0)^2}[/tex]
M = √61
The direction of the angle:
tanA = 5/6
tanA = 0.8333
A =39.80 ≈ 40 degrees
Thus, the magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.
