Answer:

h. x=8

Step-by-step explanation:

2x-7=3^2

Step 1) Square the 3

2x-7=9

2) Add 7 to both sides

2x-7(+7)=9(+7)

2x=16

3) Divide both sides by 2

\frac{2x}{2} =\frac{16}{2}

x=8

It is impossible to create a square pyramid by rotating a shape about an axis because its base is not ________.
natta225 [31]
It is impossible because it's base is not circular. A solid of revolution is <span>obtained by rotating a </span>plane curve<span> around some </span>straight line, that is, <span>the </span>axis of revolution that lies on the same plane. The closest to a square pyramid applying this concept is by rotating a right triangle around the opposite or adjacent side (the axis), but the shape that you get is a straight circular cone.

Can you please explain how you got the answer? Also plz tell me what the closed and open circle mean again..
ale4655 [162]

Answer: A

Step-by-step explanation:

  • Open circle means that x does not equal that number. For example, the open circle on C is on 8, so that shows x is not equal to 8.
  • Closed circle means that x does equal that number. For example on A, there is a closed circle on 8, so x could equal 8.

First, we need to solve the equation.

  1. Subtract 200 frim 1200 -> 125x ≥ 1000.
  2. Divide 125 from 1000 to isolate the x -> x ≥ 8

So, that means x is bigger than or equal to 8.
