Answer:
The measures of angle are 46 degrees and 134 degrees.
Step-by-step explanation:
We are given the following in the question:
Let the measure of one the of the supplementary angles be x degrees.
Measure of other angle =

Since, the two angles are supplementary, their sum is 180 degrees.
Thus, we can write and solve the equation:

Thus, the measures of angle are 46 degrees and 134 degrees.
Answer:
13x^2-4
Step-by-step explanation:
(5x^2-3)+(8x^2-1)=
5x^2+8x^2-3-1=
13x^2-4
x^2 − 8x + 9
What two numbers when multiplied yield 9 but when added yield -8?
There are no such numbers.
Use the quadratic formula.
If y represents Davids age then Davids mom is four times Davids age (4•y) plus 12 (+12). So you have
4y+12 = mom's age
