(2x2 + 3x - 5) + (-x2 + 7x + 2)

8x+1

Step-by-step explanation:

(2*2 + 3x - 5) + (-2x + 7x + 2)

1) 2*2 = 4

2) (4+3x - 5) = 3x-1

3) -2x+7x = 5x

4) 5x+2

6) 3x-1 + 5x+2

8x + 1

My answer might be wrong because i might misunderstand the 2x2 and -x2

my 2x2 what did the question  mean

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

slope is 35 and 20 miles is the y-intercept.
