7x2 + 49x - 56 What is the GCF? (If there is no GCF, type "na")

When going through the process of determining the factors after removing any possible GCFs, the two factors need to:

•add up tox
• multiply to​

na

Step-by-step explanation:

i know it already

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
