A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27
P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B
Answer:
ooo UT I did one of their courses before Now to your answer: A is Y= 7x + 2 thats the only one i know sorry
Step-by-step explanation:
I think that the answer is A.
It's a, you can just do the vertical line test where if you put a line on that graph and it hits two or more points then it isn't a function but if it only hits 1 then it is
M<1 = 360 / 3 = 120
m<2 = 120/2 = 60
m<3 = 180 - 90 - 60
m<3 = 30
answer
30 (third choice)
