Answer:
3x^3-2x^2-19x-6
Step-by-step explanation:
= 3x^2x+3x^2(-3)+7xx+7x(-3)+2x+2(-3)
= 3x^3 - 2x^2 - 19x - 6
Key - (^) means exponent
Answer:
Step-by-step explanation:
That exterior angle of 111 is equal to the sum of the triangle's remote interior angles. We add the 37 + 35 to get a total angle measure of 72. That means that the base angle on the right is 111 - 72 = 39. That 39 degree angle is vertical to x; that means that x = 39 as well.
