Answer:
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2) <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)

Choice D
Answer:
2344.79686
Step-by-step explanation:
The fifth place to the right of the decimal point is the hundred-thousandth spot. Since the number following is 7, we round up, thus resulting in 2344.79686.
Answer:

Step-by-step explanation:
Answer:
3x + 6
Step-by-step explanation:
It's A because x + x + x = 3x and 2+2+2 = 6
2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
