Find the area of a triangle​

Answer:

x = 5

Step-by-step explanation:

Given

7 + 3(2x - 5) = 3x + 7 ← distribute parenthesis and simplify left side

7 + 6x - 15 = 3x + 7

6x - 8 = 3x + 7 ( subtract 3x from both sides )

3x - 8 = 7 ( add 8 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Answer:

120$

Step-by-step explanation:

as we know the formula to calculate i is (ptr)/100

so i =(1000×6×2)/100

=(12000)/100

=120$

Answer:

6x + 20 + 4x + 80 - 2x=180

6x + 4x - 2x= 180 - 80 - 20

8x = 80

x = 10

The value of x in the triangle is 10, the value of each angle are; 80, 40 , 60 respectively

The total angle can be added as

note that the total angle in the triangle is 180

[tex]6x + 20 + 4x + 80 - 2x=180[/tex]

[tex]6x + 4x - 2x= 180 - 80 - 20[/tex]

[tex]8x = 80x = 10[/tex]

Then we can know the angles as ;

[tex]6x + 20=(6*10) +20 =80\\4x = 4*10 = 40\\80 - 2x = 80 - (2*10) = 60[/tex]

Answer:

C

explanation:

x = 4/3πr³

cross multiply

cube root both side

³√3x = ³√4πr³

³√3x = ³√4π x r

divide both side by ³√4π

r = ³√3x/4π

Answer:

slope:2

Step-by-step explanation:

Slope is rise/run, or change in y/change in x.

With that being said, we only need two points to solve this.

Let's take the points (0,7) and (1,9)

The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).

M is the slope.

y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.

x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.

Plugging those values in to the formula, we get m=(9-7)/(1-0)

Simplifying, we get m=2/1, which is m=2.

All we need to do is get the ? by itself in both equations.

-4 - ? = - 7

-? = -7 + 4

-? = -3

? = 3

? - ( -3) = 5

? + 3 = 5

? = 5 - 3

? = 2

Answer:

First ?: 3

Second ?: 2

Step-by-step explanation:

Do the inverse operation of what is shown to get the answer.

First ?:

-4 - ? = -7

-7 + 4 = -?

-3 = -?

3 = ?

Second ?:

? + 3 = 5 (Two negatives in a row make a positive.)

5 - 3 = ?

2 = ?

Step-by-step explanation:

The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The function is given below.

f(x) = 2x² + 12x + 16

The root of the equation will be given as,

f(x) = 0

2x² + 12x + 16 = 0

x² + 6x + 8 = 0

x² + 4x + 2x + 8 = 0

x(x + 4) + 2(x + 4) = 0

(x + 4)(x + 2) = 0

x = -2, -4

The solution of the quadratic equation f(x) = 2x² + 12x + 16 will be negative 2 and negative 4.

$1200 gross pay

Step-by-step explanation:

if you worked 40 hours normally and had 10 hours over time, that equation for the gross pay would be X = 20(40) + 30(10)

X = 20(40) + 30(10)

X = 800 + 300

Answer:

30

Step-by-step explanation:

For a right triangle there is a formula ---> a² + b² = c²  ("c" is always the side not touching the right angle)

24² + 18² = c²

576 + 324 = c²

900 = c²

30 = c

Opposites sides are equal in a rectangle.

Answer:

The answer is: "It has to be a rectangle.  I measured the diagonals to be sure they were the same length."

Step-by-step explanation:

The other properties are true of a rectangle as well, but they could also be other shapes.

"It has to be a rectangle.  The opposite sides are the same length."

This could also be describing a rhombus or square.

"It has to be a rectangle because it is not a square."

This could also be a rhombus, trapezoid, or even kite.

"It has to be a rectangle.  I made sure that the two 8-foot boards are parallel and that the two 6-foot boards are parallel."

This can describe any parallelogram.  Just because the sides are congruent and parallel does not mean that there are four 90degree angles formed.

"It has to be a rectangle.  I measured the diagonals to be sure they were the same length."

This is a property of rectangle diagonals.  They will always be congruent.
