Answer:
AC = 32 units
Step-by-step explanation:
It looks like DE is half of AC, so to find the length of AC you would multiply the length of DE by 2.
DE = 5x + 6, so 2(5x + 6) = AC.
Distribute the 2 inside the parentheses.
Now make this value equal to the expression standing for AC, 12x + 8.
Subtract 10x from both sides of the equation.
Subtract 8 from both sides of the equation.
Divide both sides by 2 to solve for x.
Take this value of x and substitute it into the expression for the length of AC.
Multiply 12 and 2 together.
Add 24 and 8.
AC = 32 units
the answer is 45 because of the time
