The figure is a cube
The surface area of a cube is equal to
where
b is the length side of the cube
In this problem we have
substitute
The sign would be negative
X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive
Answer:
9x^2 - 10x -4
Step-by-step explanation:
It is set up like this
9x^2 - 8x
- (x-2)2
First solve (x-2)2
the answer is (2x-4)
so now you can do this instead
9x^2 - 8x
- 2x - 4
----------------------------------
9x^2 - 10x +4
9x^2 minus zero is 9x^2
-8x-2x is -10x
0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive
A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus
like this
9x^2 - 8x
+ -2x + 4
----------------------------------
9x^2 - 10x +4
B for sure!!!!!!!!!!!!!!!!!!!
