Answer:
2 is your answer.
Step-by-step explanation:
Simplify. Remember to follow PEMDAS. First solve the parenthesis, then multiply, and finally divide.
-8(17 - 12) = -8(5) = -40
-2(8 - (-2)) = -2(8 + 2) = -2(10) = -20
-40/-20 = 2
2 is your answer.

Answer:
1 and 3
Step-by-step explanation:
The angles opposite each other when two lines cross. They are always equal. "Vertical" refers to the vertex (where they cross), NOT up/down.
We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
