2p + 3x = 680 x = 2p
svlad2 [7]
Use substitution. 

2p + 3(2p) = 680
2p + 6p = 680
8p = 680
p = 85

Plug in.
x = 2p
x = 2(85)
x = 170
p = 85

A convex parabola is shown in a coordinate plane. The parabola connects the points left-parenthesis negative 4.5 comma 12 right-
spayn [35]

Since the parabola is connecting the points, it means that the points given are on the parabola or that the points are solutions of the parabola. Thus, when we substitute the points into the function, we should end up with the correct y-value.


To find the correct choice, let's test a point. An easy point to test I believe would be (-3, 0) because we should be getting 0 as a y-value. Let's test:

A. (- 3 - 3)(3 + 4) = -42

B. (-3 + 3)(-3 - 4) = 0

C. (-3 + 2)(-3 - 4) = 7

D. (-3)(-3 + 12) = -27


We can see that Choice B is the correct function, because it produces 0 when we substitute x = - 3. Thus, Choice B, or (x + 3)(x - 4) is the answer.

A teacher is cutting pieces of tape for the marshmallow challenge.The roll of tape is 16.8 meters long and each piece measures 1
Zanzabum

Given:

Total length of tape in roll = 16.8 meters

Length of each piece = 1.125 meters

Number of pieces = 8

To find:

The remaining tape.

Solution:

We have,

Length of 1 piece = 1.125 meters

Length of 8 piece = 8 × 1.125 meters

                              = 9 meters

Total length of tape in roll = 16.8 meters

Remaining tape = Total length of tape in roll - Length of 8 piece

                           = 16.8 - 9 meters

                           = 7.8 meters

Therefore, the length of remaining tape is 7.8 meters.
