Answer: AC=15

Step-by-step explanation:

AC=AB+BC

AC=12+3

AC=15

Answer:

[tex]\frac{36}{B^2}[/tex]

Step-by-step explanation:

Given:

[tex]AB=12\\BC=3[/tex]

Find:

[tex]AC[/tex]

First, arrange equation 1 to isolate A by dividing both sides by B:

[tex]AB=12\\A=\frac{12}{B}[/tex]

Then, arrange equation 2 to isolate C by dividing both sides by B:

[tex]BC=3\\C=\frac{3}{B}[/tex]

Now, multiply A and C together and simplify:

[tex]AC=\frac{12}{B}*\frac{3}{B}[/tex]

[tex]AC=\frac{36}{B^2}[/tex]
