Answer:
Step-by-step explanation:
1. 56 + 81 = 137
2. The exterior angle theorem means that the 2 angles within a triangle that is on the opposite side of the angle outside the triangle could be added to find the angle that is outside of the triangle.
3. 56 and 81 are on the opposite side of the "x" outside the triangle which means that they could be added together which equals 137 degrees.
Hope this helps!
Gotta be red like mine. Right????
First you should ask, which two numbers add up to -10 and multiply to 9.
-9 and -1 add up to -10 and multiply to 9.
So we can factor and rewrite like this ;
Let's equal it to 0 again.
The multiplication of (x-9) and (x-1) is equal to 0
So we should equal them to 0 seperately to find the solution set
and
The solution set,
ANSWER. No, it is not equal.
Multiply 2(3-4y). It doesn’t equal it: 6-8y.
