18. G.
Step-by-step explanation:
17. To solve you have to substitute x with 5 in every equation. The answer would be the one that has a value of 12. The first equation has a value of 12:
[tex]5^2 -13 = 12[/tex]
Therefore the answer for question 17 is 12.
18. To solve you have to understand that this triangle is a 45 45 90 triangle. It is an isosceles triangle that has two sides that are equal. This means that AC = AB. Therefore, AC is equal to 10.
