I really need help with this

480 in^3

Step-by-step explanation:

The volume of the large container is

V = l*w*h = 8*10 *5 = 400 in^3

The volume of the small container is

V = l*w*h = 5*4*4 =80 in^3

Add the volumes together

V = 400+80 = 480 in^3

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

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
