78 = -6(-р-5) + бр
show steps

Step-by-step explanation:

78=-6(-p-5)+6p

distribute

78=6p++30+6p

combine like terms

78=12p+30

subtract 30 from both sides

48=12p

divide to get p by itself

p=4

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : 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
