Answer:
It's choice B.
Step-by-step explanation:
When r= -11,
x^2 + 8x - 33 = (-11)^2 - 88 - 33
= 121 - 88 - 33
= 0
- so x = -11 gives a zero value and is a solution to the equation.
Answer:
8/21
Step-by-step explanation:
1- 2/7 - 1/3 = 21/21 - 6/21 - 7/21 = 8/21
Answer:
12ft
Step-by-step explanation:
A prism is a 3D shape which has the same 2D shape repeated along its length (this is sometimes called the cross section).
The 2D shape at the ends of the prism is the base of the prism, so for this shape, the <u>bases</u> are the <u>triangles</u>.
The height of the prism is actually the length of the prism, so for this prism the height is 12 ft.
Answer:
I THINK IT IS THE LAST ONE
Step-by-step explanation:
A crater shape should look like a circle. Then, the distance around the crater would be the area of the circle. To answer this question, you need to know how to calculate circle area. Since the diameter is 4100ft and radius is 1/2 of diameter, then the area should be:
Circle area= 2* 3.14 * radius= 2 *3.14 * 1/2 * 4100ft= 12874ft
