Answer:
C
Step-by-step explanation:
The last reasoning is the side angle side theorem. In the whole proof, there is no mention of an angle. So the answer has to involve prooving that the angle in between the two sides that have been proven similar is the same in both traingles. This is best accomplished by statement C.
Answer:

Step-by-step explanation:
Given the system of equations:

You can pply Substitution method:
First you must solve for "y" from the first equation:

Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

2x + 14 + 6y (multiply everything by 2)
The slope of XY is the same as the slope of AB because XY is parallel to AB. Parallel lines have the same slope.
Answer:
343 cubic units^3
Step-by-step explanation:
its a cube which means all the sides are the same length, multiply lwh (length x width x height), which would be 7x7x7 or 7^3.
