Answer:

<h3>72x+40</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

<u><em>DISTRIBUTIVE PROPERTY:</em></u>

A(B+C)=AB+AC

A(B-C)=AB-AC

A=8

B=9x

C=5

8*9x+8*5

8*9x+8*5 (Solve.)

8*9x=72x

8*5=40

72x+40

So, the correct answer is 72x+40.

A number n is increased by 8. If the cube root of that results equals -0.5, what is the value of n?
jek_recluse [69]

The cube root of (n increased by 8), or  ∛(n+8), is -0.5, or -1/2.

∛(n+8) = -1/2.  To solve this for n, cube both sides, obtaining n+8 = -1/8.

Eliminate the fraction by mult. all three terms by 8:             8n + 64 = -1

Solving for n:  8n = -65, so that n = -65/8.
