In this question, you have to form the equation given the formula of the volume : L x W x D
L = W+5
W = W
D = W-1
(W+5)(W)(W-1) = 20
(W^2+5W)(W-1) = 20
W^3+4W^2-5W-20 = 0
Get the roots by factoring it out.
<span>(w +4) *(w +2.236) *(w -2.236)
</span>
So the roots are: -4, -2.236, 2.236.
Since we're talking about dimensions, let's use the positive root..
L = 7.24
W = 2.24
D = 1.24
Answer:
d) 80
Step-by-step explanation:
(35% = 0.35)
equation:
⇒
divide 0.35 on both sides
⇒
solve:
⇒ x = 80
Answer:
hi
Step-by-step explanation:
Distance Formula D RT
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour
