What we're dealing with is the Distributive Property. This allows any number/variable outside of a parenthesis to multiply by all numbers/variables inside of the parenthesis.
For example:
2(1 + 3)
2(1) + 2(3)
2 + 6
8.
Now that we've broken down what we're dealing with, let's try to solve.
-3(b + 19) = -12
-3(b) + -3(19) = -12
-3b -57 = -12
Add 57 to both sides to get -3b by itself.
-57 + 57 = 0
-12 + 57 = 45
-3b = 45
Divide both sides by -3 to solve for b.
-3b / -3 = b
45 / -3 = -15
b = -15

Answer:
x = 12 degrees
Step-by-step explanation:
This isosceles triangle has two equal sides and thus two equal angles. We find the measure of angle 2 by subtracting 76 degrees from 180 degrees, and then dividing the result (104 degrees) by 2: m<2 = 52 degrees.
Then m<2 = 52 degrees = 3x + 16, or
52 degrees - 16 degrees = 3x, or:
36 degrees = 3x
Thus, x = 12 degrees
They are perpendicular to
Adding a number to the variable moves the graph horizontally to the left.
The answer is B.
Answer:
No, they are not copies of each other.
Step-by-step explanation:
<XNY and <ZHC are not the same sized angles. The shapes would have the same angles if they were just scaled down copies.
