A contractor is calculating the number of decorative stones for a new rectangular patio. The bids always include a count for the number of stones for the edging, E(x), and the number of stones for the center of the patio, C(x). The various patio sizes have lengths represented by the function f(x) and widths represented by g(x).

a.

b.

c.

d.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

yes
