Answer:
(x-8)(x+7)
Step-by-step explanation:
using quadratic formula we have
x=
we have:
x^2-x-56=0
a= 1 b=-1 c=-56
so we have:
x=(-(-1)+-sqrt(1^1-4*(1)*(-56)))/(2*1)
x=1+-sqrt(1-4*(-56))/(2)
x=(1+-sqrt(225))/2
x=(1+-15)/2
so we have the roots:
x1=(1+15)/2 =8
x2=(1-15)/2=-7
so the answer is (x-8)(x+7)
Answer:
<h3>X=16</h3>
Step-by-step explanation:
Add 24 to both sides
24x/24=384/24

Answer:
It would be 45 gallons for 6ft
15 gallons for 2 feet
Step-by-step explanation:
Volume = ( length x width x height ) / 3
For the pyramid in the picture, it would be ( s x s x h ) / 3
3yx-1
i think (the -1 is an exponent)
