The length of a rectangle is 3 m more than 5 times the width. The perimeter is 126 m.
What is the length?

53m

Step-by-step explanation:

Let x = the width

Let y = the length

5x + 3 = y

2x + 2y = 126

Plug in 5x + 3 for y in the second equation

2x + 2(5x + 3) = 126

Distribute the 2

2x + 10x + 6 = 126

Combine like terms

12x + 6 = 126

Subtract 6 from both sides

12x = 120

Divide both sides by 12

x = 10

Remember x = width. You are looking for length.

y = 5x + 3

y = 5(10) + 3

y = 50 + 3

y = 53

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
