Let x be the width of the playground, then 3x is the length of the
<span>playground
х * 3х = 75
3x</span>² = 75
x² = 25
x = 5 m (width)
5*3=15 m (length)
Perimeter = 2(5+15) = 2*20 = 40 meters.
Thtas what you must mean.
The distance beteen th epoints will be sqrt(4^2 + 6^2) = sqrt 52 = 2 sqrt13
This are the right steps
Step 1: first you divide the both size by 7 because there is 7 a's
7a/7 = 28/7
Step 2: You solve the equation
7a/7= a. 28/7 = 4
So, the answer is a = 4
not 7 = 4
Answer: 
Step-by-step explanation:
Given: Sybil has 1/2 of a pizza left over.
If she share the pizza with 3 of her friends, to find the fraction of the original pizza will Sybil and her 3 friends each receive, we need to divide 1/2 by 3 we get
The fraction of the original pizza will Sybil and her 3 friends each receive

For this case we must give the result obtained by adding three times the number 15 with four times the number 2. For this we have, be "x" the result obtained when making the addition:

What is equivalent to:

Thus, the sum of three times 15 and four times 2 is 53.
Answer:
The sum of three times 15 and four times 2 is: 53.
