-3(x+2)=12. solve for x

bagirrra123 [75]

Steps to solve:

-3(x + 2) = 12

~Distributive Property

(-3 * x) + (-3 * 2) = 12

~Simplify

-3x - 6 = 12

~Add 6 to both sides

-3x - 6 + 6 = 12 + 6

~Simplify

-3x = 18

~Divide -3 to both sides

-3x/-3 = 18/-3

~Simplify

x = -6

Best of Luck!

Which equation can be used to find the surface area of the cylinder?

miss Akunina [59]

Answer:

The fourth one

Step-by-step explanation:

Surface area of a cylinder: $SA=2\pi rh+2\pi r^2$

where r = radius and h = height

We have a given height of 14cm and a given diameter of 6cm

We need the radius, not the diameter

To convert diameter to radius we simply divide by 2

6 / 2 = 3

so R = 3

We now plug in the given values into the formula

$SA=2\pi (3)(14)+2\pi (3)^2$

This equation matches with answer choice D
