All triangles interior angles equal 180
So these 3 angles = 180
Answer:
The solution is x = -3
Step-by-step explanation: Please brainliest!
Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole given a part and the percent.
We are asked to perform the long division on the following expression.
Let us perform the long division.
So, we have
Quotient: q(x) = 19x^2 - 24x + 30
Remainder: r(x) = -32
Divisor: b(x) = x + 1
Therefore, the equivalent expression is
The 3rd option is the correct answer.
