answer= 102
Step-by-step explanation:
Given,
Perimeter=46
Let, breadth=X
Then, length = 4X-7
Now,
Perimeter= 2(l+b)
46 = 2(4X-7+X)
46 = 2(5X-7)
(46)÷2 = 5X-7
23+7 = 5X
30 = 5X
30÷5 = X
:-X = 6
Also,
length = 4×6-7 = 17
breadth = 6
Then,
Dimensions = l×b
= 17×6
= 102
Answer:
the width = 6 unitsthe length = 17 unitsStep-by-step explanation:
Let 'w' be the width
The length is 7 less than 4 times the width.so the length = 4w - 7
The formula of the Perimeter is
Perimeter = 2(length + width)
46 = 2(4w - 7+ w)
46 = 2(5w- 7)
46 = 10w-14
46+14 = 10w
60 = 10w
w = 6
Hence,
the width = 6 unitsthe length = 4w - 7 = 4(6)-7= 24-7=17 unitshow do you factor 18x^2-18x-5?

enter your answer as a simplified fraction formatted like this: 42/53
the answer on there is wrong
Answer:
[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]
Step-by-step explanation:
Convert a Repeating Decimal to a Fraction
We need to convert the following decimal to a fraction:
[tex]-0.\overline{37}[/tex]
Let's call x to the given number:
[tex]x=-0.\overline{37}[/tex]
The number has two repeating (periodic) decimals, thus we multiply by 100:
[tex]100x=-37.\overline{37}[/tex]
Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:
[tex]100x - x = -37[/tex]
Operating:
99x=-37
Dividing by 99:
[tex]\displaystyle x=-\frac{37}{99}[/tex]
The fraction cannot be simplified, thus:
[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]

Answer:
whats the question?
Step-by-step explanation:
Answer:
Yes! I can help you!
Step-by-step explanation:
Where is the question?
The volume V (in cubic feet) of a rectangular room can be modeled by V(x)= 2x^3-14x^2+12x, where x is the length (in feet) if the room. Factor the function. Use your factorization to determined the values of x for which the model makes sense
Answer:
The values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].
Step-by-step explanation:
From statement we have the following expression for the volume of the rectangular room is:
[tex]V(x) = 2\cdot x^{3}-14\cdot x^{2}+12\cdot x[/tex] (1)
Where:
[tex]V[/tex] - Volume of the rectangular room, measured in cubic feet.
[tex]x[/tex] - Length of the room, measured in feet.
By Algebraic means we factorize the polynomial:
[tex]V(x) = x\cdot (2\cdot x^{2}-14\cdot x +12)[/tex]
[tex]V(x) = x\cdot (x-6)\cdot (x-1)[/tex]
Given that both volume and length must be positive variables, then the following conditions must be satisfied:
[tex]x \ge 0\,ft\,\land\,x\ge 6\,ft\,\land\,x\ge 1\,ft[/tex]
Then, the values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].

8. What is the solution of the equation 4x + 12 = 48 ?
a) x= 9
b) x= 15
c) x= 144
d) x= 240
Answer:
A) x=9
Step-by-step explanation:
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12
4x = 36
/4 /4
x = 9
The solution of the equation is, x = 9.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The equation is,
⇒ 4x + 12 = 48
Now, We can solve the equation for value of x as;
⇒ 4x + 12 = 48
Subtract 12 both side, we get;
⇒ 4x + 12 - 12 = 48 - 12
⇒ 4x = 36
Divide by 4;
⇒ 4x/4 = 36/4
⇒ x = 9

Would the answer of
-9/16+9/8
Be positive or negative? Explain why or why not.
This is a personal question!
Answer:
It would be positive
Step-by-step explanation:
To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive
Answer:
positive
Step-by-step explanation:
-9/16= -0.5625
9/8= 1.125
-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)
=0.5625
the reason
+ * + = +
- * - = +
+ * - = -
+/+ =+
- / - = -
-/ + = -
+ / - = -
⚠️⚠️WHATS THE EQUATIONS (Y=Mx+B)⚠️⚠️
Answer:
Y=-5/4+20
Step-by-step explanation:
Johnna has $440 in her savings account the first week. She deposits $65 in her account every week. How much money will Johnna have in her savings account in the 25th week?
she will have $2065 in her savings account after the 25th week.
Answer:
2,065
Step-by-step explanation:
First you need to figure out 65 times 25 because she puts $65 into her account every week so you need to multiply by 25 because you have to figure out how much money she will have on the 25th week so:
$65 * 25 = 1,625
then you need to add that to 440 because ahe still only has 440 in her account until now so, in conclusion, she has 2,065 because:
$65 * 25 = $1,625 + $440 = 2,065
