The answer is B. 35, because if the exterior angle is 95 degrees, this makes the angle on the inside 85, so that they both add up to 180 degrees. All the angle measure of a triangle add up to 180, so 60+85= 145. 180-145= 35 degrees. Hope this helped.
3x^2y^4z - 6xy - 3z(5x^2) has three terms.

I think it would be (-y) to the power of -4. The exponents would add together to equal -4 while the y would just stay the same.
