Question

Can someone please help with this? I am so confused

substitute a
-13 ; b = -9 ; C = 2 and evaluate each expression.
17. 2c + b - a + 14
18. -(-2a) + 16 - b2
19. -3b + C - a + 4

Answer 1

Basically adding in and subing the letters with the numbers given too you below

Explanation:

2(2)+(-9-13)+14= -4

-(-2(-13)+16-(-9)2= -60

-3(-9)+(2-13)+4= 48
