Note the equal sign. What you do to one side, you do to the other.

Follow PEMDAS.

First, distribute -3 to all terms within the parenthesis.

-9 = -3(x + 2)

-9 = -3x - 6

Next, do the opposite of PEMDAS. Isolate the x. Note the equal sign. What you do to one side, you do the other.

Add 6 to both sides

-9 = -3x - 6

-9 (+6) = -3x - 6 (+6)

-9 + 6 = -3x

-3x = -3

Isolate the x. Divide - 3 from both sides

-3x/-3 = -3/-3

x = -3/-3

x = 1

1 is your answer for x

SimplifyOkie dokie so first things first, you have to get rid of those parentheses! To do this you use the distributive property. -3(x+2) is the same thing as -3(x)+-3(2). that and you get -9=-3x-6. So you want to get x by itself to be able to find what x is, so you add 6 to both sides of the equation to get rid of the -6. So then you get -3=-3x. Then you must divide both sides by the coefficient of x, which would be -3. When you divide both sides by -3 you get -3/-3=x, which is the same thing as 1=x. Hope this helped!

Find the volume of the following. Please round your answer to the nearest tenth. Please do not put units. Hint: You need to use
Sophie [7]

Answer:

<em>V = 1,568</em>

Step-by-step explanation:

<u>The Volume of a Square Pyramid</u>

Given a square-based pyramid of base side a and height h, the volume can be calculated with the formula:

\displaystyle V=\frac{1}{3}a^2h

We are given a square pyramid with a base side a=14 ft but we're missing the height. It can be calculated by using the right triangle shown in the image attached below, whose hypotenuse is 25 ft and one leg is 7 ft

We use Pythagora's theorem:

25^2=h^2+7^2

Solving for h:

h^2=25^2-7^2=625-49=576

h=\sqrt{576}=24

The height is h=24 ft. Now the volume is calculated:

\displaystyle V=\frac{1}{3}*14^2*24

V = 1,568
