Answer:
m∠C = 60°
Step-by-step explanation:
First, let's start with the fact that all angles in a triangle add up to 180°. That means that:
x+3x+2x=180°
We can simplify it into:
6x=180°
To figure out x, we need to divide 180 by 6.
That means each x is 30°
m∠C = 2x
m∠C = 60°
-5x+y=-7 is the answer for this problem
Answer:
9x^3-21x^2+19x-6
Step-by-step explanation:
First you have to distribute the first equation into the second since the two are being multiplied:
(3x^2-5x+3)(3x-2)
9x^3-6x^2-15^2+10x+9x-6
(simplify)
9x^3-21x^2+19x-6
