Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.

Kitty [74]

15 + .65x = 80

15 + .65x = 80
15 - 15 + .65x = 80 - 15
.65/.65x = 65/.65
x = 100
Beth swam 100 laps.

Answer:

i know the answer for question 8 & 9

8) Volume is the amount of space a 3D shape takes up.

A cubic cm block takes up 1 cubic cm. This is written as 1 cm³.

You can work out the volume of a shape by multiplying height × width × depth.

If the shape is made of cubic cm blocks, you can count the cubes to find the shape's volume.

9) The face or surface of a solid on its sides. That is, any face or surface that is not a base. See also. Lateral surface area, prism, pyramid, cone, cylinder.

Use the grouping method to factor this polynomial completely.<br> 3x3 + 12x2 + 2x + 8

dezoksy [38]

Answer:

(3x^2 + 2)(x + 4).

Step-by-step explanation:

3x3 + 12x2 + 2x + 8

3x^2(x + 4) + 2(x + 4) The x + 4 is common to the 2 groups so we have:

(3x^2 + 2)(x + 4).
