Answer:
D
Step-by-step explanation:
The sum of supplementary angles is 180°
To find the supplement of 60° subtract it from 180°, that is
second angle = 180° - 60° = 120° → D
Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.
The answer is b because it shows
Answer: 2x3 + 17x2 + 25x - 50
Step-by-step explanation: Just try to distribute it at every step as follows:
Step 1: Start with the following:
(a + b + c)(d + e)
Step 2: Distribute (d + e) to each of the term in the first parenthesis
a(d + e) + b(d + e) + c(d + e)
Step 3: Distribute d and e to each term:
(ad + ae) + (bd + be) + (cd + ce)
or ad + ae + bd + be + cd + ce without the parentheses.
Step 4: Finally, simplify.
Using the above you should be able to do the following
Step 1: (2x2 + 7x - 10)(x + 5)
Step 2: 2x2(x + 5) + 7x(x + 5) - 10(x + 5)
Step 3: 2x3 + 10x2 + 7x2 + 35x - 10x - 50
Step 4: 2x3 + 17x2 + 25x - 50
