Answer:
D) Distributive property
Step-by-step explanation:
We use distributive property because the 8 is distributed to the 7 and the negative three (it is negative because the expression can also be written as 8(7 + -3). This is how it will look after the distributing:
56 + -24
Angle KMQ and angle RNL are on apposite sides of the transversal and between above and below (exterior to) the parallel lines, so they are alternate exterior angles. Theorem - Alternate exterior angles formed by parallel lines and a transversal have the same measure.
You would use the Pythagorean there on which is a^2+b^2=c^2, from there you plug int what they gave you and solve for b, and b=12
Answer: x = 39 because 39 + 102 = 141 and 180 - 141 = 39
A.) Lines J and k because parallel lines have the same slope but NOT y-intercept.
