What is the solution to the following equation: 3x^2 + 3 = -6x

x = -1

Step-by-step explanation:

Add -6x to both sides to get: 3x^2 + 6x + 3 = 0

Factor out 3: 3(x^2 + 2x + 1) = 0

Factor inside the parentheses: 3(x + 1)(x + 1) = 0

Zero Product Property: x + 1 = 0

Solve: x = -1

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
