Answer:
see explanation
Step-by-step explanation:
let w represent the width then length = w + 7
The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14
The perimeter is given as 54 m, thus
4w + 14 = 54 ( subtract 14 from both sides )
4w = 40 ( divide both sides by 4 )
w = 10
Thus
width of playground = w = 10 m
length of playground = w + 7 = 10 + 7 = 17 m
Answer:
35 seconds
Step-by-step explanation:
if you simply minus 7 seconds from max 42 second time you get 35 seconds.
<span>4.8 (x+4)=2.6
Use distributive property
4.8x + 19.2= 2.6
Subtract 19.2 from both sides
4.8x = -16.6
Divide 4.8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x = -3.458</span>

Answer:
Option A.
Step-by-step explanation:
The given equation is
Liliana wants to write an equivalent expression.
It can be written as
Using commutative property, we get
![[\because A+B=B+A]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2BB%3DB%2BA%5D)
Using associative property, we get
![[\because A+(B+C)=(A+B)+C]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2B%28B%2BC%29%3D%28A%2BB%29%2BC%5D)
Using distributive property, we get
![[\because An+Bn=(A+B)n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20An%2BBn%3D%28A%2BB%29n%5D)
Using addition property, we get
Therefore, the correct option is A.
