Answer:
The answer is
20x + 17.5
Step-by-step explanation:
Multiply the 5 by the numbers inside the parenthesis.
5 x 4x
5 x 3.5
Answer:1608.5
Step-by-step explanation:
9514 1404 393
Answer:
162 degrees
Step-by-step explanation:
Angles P and F are supplementary, so ...
3x^2 +12x = 180
x^2 +4x = 60
x^2 +4x -60 = 0
(x +10)(x -6) = 0
The useful value of x that makes this true is x=6.
The measure of angle Q is 3x, so is 3·6 = 18 degrees. The measure of angle S is the supplement to that:
∠S = 180° -18° = 162°

Answer: Choice B) 13</h3>
You chose the correct answer.
======================================================
Explanation:
Lines M and L are only parallel if and only if the corresponding angles are congruent.
The angles 127 and (9x+10) degrees are corresponding angles. They are both on the same side of the transversal, and they are to the right of each parallel line.
Set the two angle expressions equal to one another. Solve for x
9x+10 = 127
9x = 127-10
9x = 117
x = 117/9
x = 13
