Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart. Algebraically determine the x-value of where the beam should be placed. Explain where to place the beam.

Graph the two struts on the model of the roller coaster. Take a screenshot of your graph and paste the image below, or sketch a graph by hand. (5 points)

Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart.

•Algebraically determine the x -value of where the beam should be placed. (15 points)

root(x + 8) = 2 + rootx − 4)

x + 8 = 4 + 4root(x − 4) + x − 4

8 = 4root(x − 4)

2 = root(x − 4)

x − 4 = 4

x = 8

•Explain where to place the beam.  (10 points)

The beam should be places 8 feet apart.

Step-by-step explanation:

I don't have a graph. Correct on E2020

Hope that this helps. If someone finds a graph i have a question on my page that needs it

Peace and love

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

answer is b  

20

hope you get this one right.
