4p² + 7q²
if p = -3 and q = -2

64

Step-by-step explanation:

When p= -3, q= -2,

4p² +7q²

= 4(-3)² +7(-2)²

= 4(9) +7(4)

= 36 +28

= 64

25

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
