Answer:
x = 0 or x = 3
Step-by-step explanation:
This is a quadratic equation, but because the constant term is zero, we can speed up the solution by factoring 12x^2 - 36x = 0:
12(x^2 - 3x) = 0, or
12(x)(x - 3) = 0
Thus, either x = 0 or x = 3
Tow ratios that have the same value when simplified.

Answer:
cosB = 2√6 / 7
Step-by-step explanation:
use the pythagorean theorem to find the missing side
a² + b² = c²
a² + 5² = 7²
a² + 25 = 49
a² = 24
a = √24
a = 2√6
--------------------------
cosB = adj/hyp
cosB = 2√6 / 7
Six million, seven hundred and thirty five thousand, eight hundred and thirty four
