I thought it was 2 but it’s not one of the answers :3,4,5,or 6 cans?

6 cans

Step-by-step explanation:

4 cans

Step-by-step explanation:

The total area is 2(L * H) + 2(W * H) or

2(20 * 10) + 2(15 * 10)

= 2*200 + 2*150 = 700 total sq ft.

Since one can covers 350, then 700/350 = 2 cans, BUT they want 2 coats so

double it (2*2=4).

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

the answer is d. (1.2, -4.7) on edgn

hope this !
