You will need 120 feet of fencing to put all the way around a rectangular garden. the length of the garden is 40 feet. what is the width?

Answers

Perimeter = 2L + 2w = 120

Plug in L = 40

2(40) + 2w = 120

Solve for w

2w = 120 - 80 = 40

w = 20

If JK = 4, KL = 3x, and JL = 7x, what is JL? Simplify your answer and write it as a proper fraction, mixed number, or integer.

Answers

Answer:

JL = 7

Step-by-step explanation:

If JK = 4, KL = 3x, and JL = 7x, what is JL?

From the diagram given in tbe question,

JK + KL = JL

4 + 3x = 7x

Collect like terms

4 = 7x - 3x

4 = 4x

4x = 4

x = 4/4

x = 1

Since JL from the diagram = 7x

Hence:

7 × 1 = 7

JL = 7
