The value of m is 3.

Solution:

Given equation:

6 + 5(m + 1) = 26

<u>To solve the equation:</u>

6 + 5(m + 1) = 26

Multiply 5 into each term inside the bracket.

6 + 5m + 5 = 26

5m + 11 = 26

Subtract 11 on both sides, we get

5m = 15

Divide by 5 on both sides, we get

m = 3

The value of m is 3.

Checking:

6 + 5(m + 1) = 6 + 5(3 + 1)

                    = 6 + 5(4)

                    = 6 + 20

                    = 26

6 + 5(m + 1) = 26.

Hence the solution is correct.

To find the area of the shaded region you need find the area of the shaded region and subtract the area of the unshaded region.

Area of a rectangle = width x length

A = (x + 10) x (2x + 5)

Next apply FOIL or First Outer Inner Last

A = (x * 2x) (x * 5) (10 * 2x) (10 * 5)

A= 2x2 + 5x + 20x + 50

A= 2x2 +25x +50

 

Area of a square=  sides2

A= (x + 1)2

A= (x+1) (x+1)

Next apply FOIL or First Outer Inner Last

A = (x *x) (1*x) (1*x) (1*1)

A = x2 + 1x + 1x +1

A= x2 + 2x +1

 

A= 2x2 +25x +50 - 2x2 +25x +50

A= 50x + 100

The formula for the volume of a cylinder is v= 3.14r^2h. A cylinder has a volume of 300x feet ^3 and a radius of 5 feet
Fudgin [204]

Answer:

Height = 3.82

Step-by-step explanation:

(3.14)(5)²

(3.14)(25)

= 78.5

300 = 78.5h

300/78.5 = 78.5h/78.5

h = 3.821656051 or approximately 3.82
