Indicate which property is illustrated in step 4.
step 1 (-9) + 9 + 5(7 + 3) = (-9) + 9 + (5 • 7) + (5 • 3)
step 2 = (-9) + 9 + (35) + (15)
step 3 = (-9) + 9 + 50
step 4 = 0 + 50
step 5 = 50
associative property of multiplication
commutative property of division
inverse property of multiplication
inverse property of addition

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
