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:
x=12
Step-by-step explanation:
25°+114°+(5x-19)°=180°
139°+(5x-19)=180°
5x-19=180-139
5x-19=41
5x=41+19
5x=60
x=60/5
x=12
Answer:
30%
