How do you simplify
-7x -4 (x - 3x)

Multiply the bracket by -4 first

-7x-4x+12x

= -11x+12x

= x

The answer is x. You distribute the -7x-4 into the things in the parenthesis

the probability is 0

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
