Can someone explain how you find the answer!

21m

Step-by-step explanation:

So for the rectangle, do 5*6, and you will get the area of the whole backyard. Then to get the area of the grass, you do 3*3 to get 9.

Finally, to get the cement, you subtract the area of the grass from the area of the whole backyard so 30-9 to get 21.

5*6=30

3*3=9

30-9+21

Please mark brainliest if you can!

Funny, I think you put the question in 2 times, this is the second time I'm answering this same question by you. :D

is there a picture

step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
