Answer:

B

Step-by-step explanation:

Use the pythagorean theorem

a² + b² = c²

a² + 63² = 65²

a² + 3969 = 4225

a² = 256

a = 16

x = 16 meters

Answer:

B. 16 meters

Step-by-step explanation:

Use Pythagorean Theorem to find the value of x

63² + x² = 65²    Simplify

3969 + x² = 4225

-3969         - 3969     Subtract 3969 from both sides

x² = 256                     Take the square root of both sides

x = 16

The length of a rectangular garden is three feet less than twice it’s width. If the perimeter of the garden is 42 feet, what is
Masja [62]

Answer:

The length of a rectangular garden is: 13 feet

Step-by-step explanation:

You have 2 lengths that are 2x-3 feet, and 2 widths that are x.

2x-3 + 2x-3 +x +x =42 feet

4x -6 +2x -42 feet

6x -6 = 42 feet

6x = 48 feet

x = 8 feet (so, 2x-3 = 16-3 = 13 feet)
