So a box has 5.2 oz
it takes 0.7 oz to clean one load
with 3 boxes (3 times 5.2) how many can be cleaned
3 times 5.2=15.6
15.6/0.7=156/7 how many loads=22 and 2/7 =22.285 loads or less than 22 loads (since you can't clean a decimal of a load)
22 Loads is the answer
To find x- intercepts
y = 0
(x+4)(x-2)=0
x+4=0 or x-2 = 0
x = -4 or x = 2
And the vertex will be (-1,-9)
The correct option is (B)
0.08, 5/9, 0.785, 79%, 4/5
1/2 times 1/4 = 1/8
