I just worked this question. None of those are the answers
First we remove the brackets:
4x + 16 = 2x + 4
Group like terms:
4x - 2x = 4 - 16
Evaluate:
2x = -12
x = -12/2 = -6
Answer:
130 ft^2
Step-by-step explanation:
SA= surface area
SA= 2*l*w + 2*l*h + 2*w*h
l= length = 10
w= width =5
h = height = 1
SA= 2*l*w + 2*l*h + 2*w*h
SA= 2*10*5 +2*10*1+2*5*1
SA= 100+20+10
SA= 130 ft^2
"2 minus root 3" => 2 - sqrt(3)
x does not appear here. That could cause a problem.
Unsure of what you mean by "x minus one upon X whole cube." Would you please go back to the original question and ensure that you have copied it down precisely. Without "x" in your equation, there's nothing to solve for.
Answer:
Draw a picture and you'll see a right triangle with sides = 7 and 24 and hypotenuse = r (the cricle's radius). By the Pythagorean Theorem:
r2 = 72 + 242
Area = pi·r2
Step-by-step explanation:
The answer is 31/35
Hope it helps!
