Each face of the cube has an area of 4cm^2 (2*2 = 4). A cube has six faces so the total surface area is 24cm^2 (4cm^2*6).
Length=x
width = x+7
Area =length* width =x(x+7)=170
x^2+7x=170
x^2+7x-170=0
Answer:
2 + 2 is 4

<h3>
Answer:</h3>
9² or 9^2
<h3>
Step-by-step explanation:</h3>
Because the base is the same on the top and the bottom which is "9", you would either add or subtract the top and bottom exponent based on the arithmetic symbol used.
Because the arithmetic symbol division sign is used, you subtract the top exponent by the bottom giving you the answer nine to the power of two.
