Answer:

<h3>C. -9x-3</h3>

Step-by-step explanation:

Use distribuitve property.

<u><em>DISTRIBUTIVE PROPERTY</em></u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-3x-6x-8+5 ← (Group like terms & combine like terms.)

-3x-6x=-9x ← (Add and subtract elements to the numbers from left to right.)

-9x-8+5

-9x-8+5 ← (Solve & simplify)

-8+5 ← (Add & subtract.)

-8+5=-3

= -9x-3

\Large\boxed{\mathsf{\Rightarrow -9x-3}}}

Therefore, the correct answer is (C.) -9x-3.

The pyramid shown has a height of 14 inches and a base area of 60 in2. Find the volume of the pyramid.
Kamila [148]

Volume of pyramid is 280 in^{3}.

The pyramid has a height 14 inches and a base area of 60 in2.

What is volume?

Volume is a three - dimensional quantity that is used to measure the capacity of a solid shape.

Volume of the pyramid = Area base X \frac{height}{3}

                                    = 60.\frac{14}{3}

                                    = 280 in^{3}

So the volume of pyramid = 280 in^{3}

Me pueden ayudar a saber el resultado y la operacion de la ecuacion 8-5x=8+2x por favor me urge
Art [367]
Solve for x:
8 - 5 x = 2 x + 8
Subtract 2 x from both sides:
8 + (-5 x - 2 x) = (2 x - 2 x) + 8
-5 x - 2 x = -7 x:
-7 x + 8 = (2 x - 2 x) + 8
2 x - 2 x = 0:
8 - 7 x = 8
Subtract 8 from both sides:
(8 - 8) - 7 x = 8 - 8
8 - 8 = 0:
-7 x = 8 - 8
8 - 8 = 0:
-7 x = 0
Divide both sides of -7 x = 0 by -7:
(-7 x)/(-7) = 0/(-7)
(-7)/(-7) = 1:
x = 0/(-7)
0/(-7) = 0:
Answer: x = 0
