1. Factor the polynomial. (2 polnts)
-3x4 - 9x3 + 15x2
2. Use the grouping method to factor the polynomial below completely. (4 points)
10x3 - 35x2 + 6x - 21

-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)

10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)

Step-by-step explanation:

-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)

10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)

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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
