The surface area of a cube is given by the following equation where <em>s</em> is the length of a side:

So, in this case, s is equal to 5:

Group up the like terms and combine them
2x^2 and -7x^2 add up to -5x^2
6x and 2x add up to 8x
1 and -3 add up to -2
We end up with -5x^2 + 8x - 2
<h3>Answer: Choice B</h3>
To calculate the diameter of a circle, multiply the radius by two.
Answer:
Step-by-step explanation:
The area of the rectangle is 3x(2x+5)=6x^2 + 15x
The are of the triangle is 2(x-3)/2 = x-3
Now subtract the triangle are from the rectangles area
6x^2 + 15x - x + 3 = 6x^2 + 14x + 3
