5a – 7b + b^2 for a = –1 and b = 5.

5(-1) - 7(5) + 5^2;

= -5 - 35 + 25;

= -15

5(-1) - 7(5) + 5^2;

= -5 - 35 + 25;

= -15

Evaluate the expression for a = –1 and b = 5.

5a – 7b + b^2

= 5*(-1) - 7*5 + 5^2

= -5 - 35 + 25

= -40+ 25

= -15 .

5a – 7b + b^2

= 5*(-1) - 7*5 + 5^2

= -5 - 35 + 25

= -40+ 25

= -15 .

Solve the equation. SHOW YOUR WORK. 3x - 7 = 5x + 19 and then check your answer **Weegy:** 3x - 7 = 5x + 19 3x - 5x = 19 + 7; -2x = 26; x = 26/-2; x = -13;
Check:
3(-13) - 7 = 5(-13) + 19;
-39 - 7 = -65 + 19;
-46 = -46

1. Simplify the expression. Show your work.
22 + (32 – 42)
**Weegy:**
22 + (32 – 42)
= 22 + (-10)
= 22 - 10
= 12
