Side of the room = x.
From the right triangle, where sides of the square are legs of the right triangle, and the diagonal of the square is a hypotenuse of the right triangle.
x²+x²=6²
2x²=36
x²=18
x=√18 =√(2*9)=3√2≈4.2m
Answer:
500 feet because D and B is too close and C is in the middle. I would go with A.
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
Answer:
x = -3/4
Step-by-step explanation:
<u>Step 1: Identify the equation</u>
8x + 3 = 4x
<u>Step 2: Move x's to one side and number to the other side</u>
8x + 3 - 4x - 3 = 4x - 4x - 3
4x = -3
<u>Step 3: Make x by itself</u>
4x / 4 = -3 / 4
x = -3/4
Answer: x = -3/4
Answer:
A. x > 20
