alexandr1967 [171]

Hello from MrBillDoesMath!

Answer:

c = d/a + b

Discussion:

I think the Question is missing a comma. Assuming you are trying to find the value "c",

a(c-b) = d => divide both side by "a"

(c-b) = d/a => add "b" to both sides

c-b + b = d/a + b => as -b + b = 0

c = d/a + b

Thank you,

Which statement about the equation 3x ^ 2 + 9x - 12 = 0 is true ? 1 . The product of the roots is -12 . 2 The product of the roo

svetlana [45]

Answer:

Option : The product of the roots is - 4

Step-by-step explanation:

$3x^2 + 9x - 12 = 0\\\\3x^2 + 12x - 3x - 12 = 0\\\\3x(x+4) -3(x+4) = 0\\\\(3x - 3) (x+ 4) = 0\\\\$

Therefore the roots are -4 and 1

The product of the roots are -4 x 1 = -4

A cylinder has a circular base with a diameter of 12 ft the height of the cylinder is 4 feet what is the volume of the cylinder

Murrr4er [49]

Answer:

$452\ ft^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$r=12/2=6\ ft$ ----> the radius is half the diameter

$h=4\ ft$

substitute the values

$V=(3.14)(6^{2})(4)=452\ ft^{3}$
