Im guessing he answered 30 correct, let me know if im correct
<span>As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases.</span>
Lines m and n are parallel.
Lines k and l are parallel.
Hope this helps :)
The Pythagorean Theorem is a^2 +b^2 = c^2, where a and b are the sides and c is the hypotenuse ( angled line).
3.
a^2 + 6^2 = 18^2
a^2 + 36 = 324
a^2 = 324 - 36
a^2 = 288
a =√288
a = 12√2
4.
a^2 + 3^2 = 9^2
a^2 + 9 = 81
a^2 = 81-9
a^2 = 72
a = √72
a = 6√2
