Answer:
The value of the exterior angle is 
Step-by-step explanation:
we know that
The sum of the interior angle plus the exterior angle is equal to 
, because are supplementary angles.
Let
x-----> the measure of the exterior angle
so
solve for x
3.92/2.8=1.4
Unless it’s reverse.
2.8/3.92=0.714285714285 and so on.
-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.
Answer:
B. Negative
Step-by-step explanation:
We are given that x equals negative and y equals positive.
That means the fraction is negative multiplied by the 7y³ term, which is positive.
Negative times positive is negative, so B is our answer.
6x+12y-6z+7x7y-28z= 13x+19y-34z
