Question

A: a2 - 2ab + b2; if a = -3 and b = -4 B: 2m - n) ÷ (p - 3); if m = -2, n = 4, and p = -5

Answer 1

Answer:

1

3/2

Step-by-step explanation:

Given:

a² - 2ab + b²;

If a = -3 and b = -4

2(m - n) ÷ (p - 3);

If m = -2, n = 4, and p = -5

Computation:

a² - 2ab + b²;

If a = -3 and b = -4

(-3)² - 2(-3)(-4) + (-4)²

9 - 24 + 16

= 1

2(m - n) ÷ (p - 3);

If m = -2, n = 4, and p = -5

2(-2-4) ÷ (-5 - 3)

-12 / -8

= 3/2
