An expression is shown below: 4ck2 + 10k2 − 16ck − 40k
Part A: Rewrite the expression by factoring out the greatest common factor.
Part B: Factor the entire expression completely. Show the steps of your work.

2k(k-4)(2c+5)

Step-by-step explanation:

4ck² + 10k² - 16ck - 40k

2k²(2c + 5) -8k(2c + 5)

(2c + 5)(2k² - 8k)

(2c + 5)[2k(k - 4)]

2k(k-4)(2c+5)

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

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
