A square painting has a side length of 18 inches. What is the area of the painting?

Hi! So because all the sides of the square are the same side, you multiple two of the side lengths together, so the area of the painting is 18 x 18 = 324 :) Good luck and do well in school!!!!!!!!

A square is a shape with equal sides so if the length is 18 in, the width would also be 18 in.
And to find the area of a square you multiply LxW
So, you multiply 18x18= 324 in
The area of the painting would be 324 inches.

Answer:

144

Step-by-step explanation:

20×12=240

add 4 to 20 and 12

Answer:

x = 8

y = -7

Step-by-step explanation:

(-3y) - 4x = -11

3y - 5x = -61

-----------------------+

-9x = -72

x = 8

3y - 5x = -61

3y -5(8) = -61

3y - 40 = -61

3y = -21

y = -7

Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)

QveST [7]

Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)$

So the midpoint of your segment is

$\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)$

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.
