Answer:

4(-5a + 3b - 2)

Step-by-step explanation:

Aside from changing the order of the terms so that the "a" term comes first and the "b" term second, there's nothing you can do with this expression -20a -8 + 12b. But notice that 4 is a factor common to all three terms, and therefore it can be factored out:

Rearranging the terms, we get

-20a + 12b - 8 = 4(-5a + 3b - 2)

(10)(11) Geometry Check Ans 10) 5 11) x = 33 y = 38 z = 109

ICE Princess25 [194]

Problem 10

You are correct. You divide 360 over the exterior angle measure to get 360/72 = 5

=========================================================

Problem 11

x = 33 is correct as this angle is an alternate interior angle pair with the 33 degree angle up top

y = 38 is correct since y+33+109 = 180 solves to y = 38. In other words: 38+33+109 = 180

z = 109 is correct. The opposite angles of a parallelogram are congruent
