Consider the equation 3p – 7 + p = 13. What is the resulting equation after the first step in the solution?
A) p – 7 = 13 – 3p
B) 2p – 7 = 13
C) 3p – 7 = 13 – p
D) 4p – 7 = 13

D) 4p – 7 = 13

Step-by-step explanation:

The first step is to combine like terms:

Combine 3p and p

3p – 7 + p = 13

3p + p – 7 = 13

4p – 7 = 13

This equation is the same as answer choice D, so our answer is correct.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
