Answer:

x = 9 1/2                          x = -2 1/2

Step-by-step explanation:

5-3|2x-7|=-31

Subtract 5 from each side

5-5-3|2x-7|=-31-5

-3|2x-7|=-36

divide by -3

-3/-3|2x-7|=-36/-3

|2x-7|=12

There is a positive and negative solution to the absolute value equation

2x-7 =12                2x -7 = -12

Add 7 to each side

2x-7+7 =12+7         2x-7+7 = -12+7

2x = 19                       2x = -5

Divide by 2

2x/2 = 19/2                2x/2 = -5/2

x = 9 1/2                          x = -2 1/2

ElenaW [278]
First, move 9x^2 to the right:

7y^2 = 42 - 9x^2

Then, divide 7 on both sides:

y^2 = 6 - 9/7 * x^2

m_a_m_a [10]

Answer:

122.7792 sq. m

Step-by-step explanation:

diameter= 8.4 m

therefore, radius = r = 4.2 m.......( as radius is 1/2 of diameter)

height = h= 12 m

only the exterior is to painted so the total surface area of the cylinder is taken,

total surface area of cylinder = 2π r( h+r)

=2* 3.14* 4.2*(12+4.2)

=122.7792 sq. m
