Create expressions for the length and width of the rectangle.

  • length (l): x - 6
  • width (w): x

Perimeter: 2l + 2w

Substitute (x - 6) for l and (x) for w.

  • 52 = 2(x - 6) + 2(x)

Distribute 2 inside the parentheses.

  • 52 = 2x - 12 + 2x

Combine like terms.

  • 52 = 4x - 12

Add 12 to both sides.

  • 64 = 4x

Divide both sides by 4.

  • x = 16

Substitute 16 for x into the length and width of the rectangle.

  • length: (16) - 6 = 10
  • width: (16) = 16

snow_lady [41]

Answer:

see this and it by your own

Step-by-step explanation:

How do you find average speed with distance and time?

Divide the distance by the time.

This will give you the average speed per unit of time, usually hour. So, if Ben traveled 150 miles in 3 hours, his average speed is 50 miles per hour

How do you find average speed with hours and minutes?

How to calculate average speed. Speed is distance divided by time. Simply put, if you drove 60 kilometer's for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.

Charles is 20% heavier than Edith. If Charles weighs 60kg, what is Edith's weight?​
ddd [48]

Charles' weight = Edith's weight + 20% of Edith's weight

We'll use a variable to represent Edith's weight, x.

The decimal form of 20% is 0.2.

60 = x + 0.2x

60 = 1.2x

x = 50

Edith's weight is 50kg.

Hope this helps!
