I think the answer is going to be a
Answer:
Step-by-step explanation:
Area = L x W gym area is (5x + 5x) ft² if W = 5x Find the L
Area = L x W divide both sides by W
Area/W = (L x W) / W
Area/W = L = Area/W
L = Area/W
= (5x + 5x) / (5x)
= 5x( 1 + 1) / 5x
= 5x(2) / 5x the 5x's cancel each other 5x/5x = 1
= 2 ft I got 2. I suspect the 12 was a typo and should have been 2
Answer:

Step-by-step explanation:
We have the expression:

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x
We will get:

Now we can directly add the terms to get:

We can't simplify this anymore
Answer:
4
Step-by-step explanation:
the figures are
0,0,3,8,1,0
we repeat 0
so we have 4 figures,
0,3,8,1
Answer:
