A rectangle has a length of (x + 3) centimeters and the width of x centimeters. The perimeter of a rectangle is 26 centimeters. Find the length of the rectangle, in centimeters. *

8 cm

Step-by-step explanation:

The perimeter of a rectangle is found by

P = 2(l+w) where l is the length and w is the width

We are given l = x+3 and width is x and the perimeter is 26

26 = 2( x+3 +x)

Combine like terms

26 =2(2x+3)

Divide each side by 2

26/2 =2/2(2x+3)

13 = 2x+3

Subtract 3 from each side

13-3 = 2x+3-3

10 =2x

Divide each side by 2

10/2 =2x/2

5 = x

We want to find the length

length = x+3

          = 5+3

          =8 cm

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
