Answer:
b 8
Step-by-step explanation:
just replace the z with a 2 and solve
3(2)+2
There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. Multiplicative Identity Property: The product of any number and one is that number. For example 5 * 1 = 5.
Given that the triangle is isosceles, we can say that AB = AC. Using the given expressions we can form the following equation.
![\begin{gathered} AB=AC \\ 5x+8=7x-6 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20AB%3DAC%20%5C%5C%205x%2B8%3D7x-6%20%5Cend%7Bgathered%7D)
Let's solve for x.
![\begin{gathered} 8+6=7x-5x \\ 14=2x \\ x=\frac{14}{2} \\ x=7 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%208%2B6%3D7x-5x%20%5C%5C%2014%3D2x%20%5C%5C%20x%3D%5Cfrac%7B14%7D%7B2%7D%20%5C%5C%20x%3D7%20%5Cend%7Bgathered%7D)
Once we have the value of the variable, we can find the length of AC.
![\begin{gathered} AC=7x-6 \\ AC=7(7)-6 \\ AC=49-6 \\ AC=43 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20AC%3D7x-6%20%5C%5C%20AC%3D7%287%29-6%20%5C%5C%20AC%3D49-6%20%5C%5C%20AC%3D43%20%5Cend%7Bgathered%7D)
<h2>Therefore, the length of AC is 43.</h2>
