The answer would be A!
The reason it's A is because you have two arrors on the number line! Hope this helps with your odyssey ware work!
23+23+16+16=78
78 is the perimeter:)
F = 1/2 J = 2M
J = 4M
M + F + J = $280
M + 2M + 4M = $280
7M = $280
M = $280/7 = $40
J = 4M = 4x40 = $160
F = 1/2 (160) = $80
40 + 160 + 80 = $280
Mary saved $40
Fred saved $80
John saved $160
Set up proportions
8/28=5/21
8*21=168
5*28=140
so no, they are not equivalent
tha range of the function is all real number greater than 0
