Answer:
3x^3-18x^2+26x-8
Step-by-step explanation:
(x-4)(3x^2-6x+2)
3x^3-6x^2+2x-12x^2+24x-8
3x^3-18x^2+26x-8
<u><em>780 students</em></u>
<u><em></em></u>
<em>Set up a proportion.</em>
<em />
<em>75 / 125 = x/1300</em>
<em />
<em>125 10.4 = 1300</em>
<em />
<em>75 * 10.4 = 780</em>
<em />
<em>x=780</em>
Answer:
= 440 ft
Step-by-step explanation:
The perimeter of a rectangle is found by adding up all the sides. We use the formula
P =2(l+w)
where l is the length and w is the width
The length is 140 and the width is 80
P = 2(140+80)
= 2(220)
= 440 ft
The input is the hours and the out put is the cost.
