What values of x make the equation 3x^2+6x=-18

No solution

Step-by-step explanation:

Equation: 3x² + 6x = -18

Divide by 3: x² + 2x = -6

Add: x² + 2x + 6 = 0

Quadratic formula: x = (-2 ± √((-2)² - 4(1)(6))/2

Multiply: x = (-2 ± √(4 - 24))/2

Solve the discriminant: 4 - 24 = -20

When the discriminant is negative, there is no solution because square roots can not be negative.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
