Answer: 54x^2+360x+600</h3>
==========================================================
Explanation:
One square face has an area of
(length)*(width) = (3x+10)(3x+10) = 9x^2+30x+30x+100 = 9x^2+60x+100
after using the FOIL rule
Multiply that by 6 to get the total area of all 6 faces
6*(9x^2+60x+100) = 54x^2+360x+600
The surface area units are in square feet.
Answer:
To find it, add together all of your values and divide by the number of addends.
Two equations
W*L=1260
3W+48=L
Solve
L=1260/W
3W+48=1260/W
3W^2+48W=1260
3W^2+48W-1260=0
Divide by 3
W^2+16W-420=0
Factor
(W-14) (W+30)
W=14
L=90
