D.) There are always 180 degrees in triangles. 147 is already shown, so subtract that from 180. That gives you 33.
You can use prime factorization to find the GCF of a set of numbers. This often works better for large numbers, where generating lists of all factors can be time-consuming.
Here’s how to find the GCF of a set of numbers using prime factorization:
* List the prime factors of each number.
* Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
* Multiply all the circled numbers.
The result is the GCF.
For example, suppose you want to find the GCF of 28, 42, and 70. Step 1 says to list the prime factors of each number. Step 2 says to circle every prime factor that’s common to all three numbers (as shown in the following figure).
As you can see, the numbers 2 and 7 are common factors of all three numbers. Multiply these circled numbers together:
2 · 7 = 14
Thus, the GCF of 28, 42, and 70 is 14.
A is parallel to C and B is parallel to D...
Answer:
C ) y = -2x
Step-by-step explanation:
(2, -4)
y = -2x
subsitute x for the value of x
y = -2(2)
-2 × 2 = -4
y = -4
so
the equation for the point (2, -4) is
y = -2x
Answer:
4, 1, 6.

Step-by-step explanation:
You are given the equation
First subtract from both sides:
and multiply the equation by -1:
Now multiply (1) by 2:
At last, divide by
