The perimeter of a rectangle is 90 feet. if the length is 25 feet more than the width, what are the dimensions of the rectangle?

Width = 10 feet

Length = 2x + 4

Length = 2 (10) + 4

Length = 24 feet

Dimensions are 10 feet by 24 feet.

Step-by-step explanation:

The perimeter of a rectangle is the length of all 4 sides added together. Since it is a rectangle, we know that it has 2 pairs of identical parallel sides, so the perimeter will be 2 × the length plus 2 times the width. The problem gives us some key information so that we can solve for the dimensions. If we let x equal the width, the length will be 2x + 4 so the equation will be...

2(x) + 2 (2x + 4) = 68

2x + 4x + 8 = 68

6x + 8 = 68

6x = 60

x = 10

Since we made the width x...

Width = 10 feet

Length = 2x + 4

Length = 2 (10) + 4

Length = 24 feet

Dimensions are 10 feet by 24 feet.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
