Answer:
X= 38
Step-by-step explanation:
A straight line is 180⁰ so we can subtract that by 133⁰ to get the degree on the inside of the triangle which is 47. You then add 47 and 95 to get 142. To get x you subtract 142 from 180
the correct answer for this is b
"Factor by grouping" generally means you divide the 4 terms into groups of 2 terms.
.. (5x^2 +40x) -(x +8)
Now, you factor each group.
.. 5x(x +8) -1(x +8)
Now, you factor out the common factor, x+8.
.. (5x -1)(x +8)
