For every one stamp James has Roy has twice as much. So the ratio would be 1/2. Hope this helped!
the domain: no real numbers so its negative infinity, positive infinity
P = 77.
side (S1, S2) = 2(B) - 4.
P = S1 + S2 + B.
77 = (2B - 4) + (2B - 4) + B.
77 = 2B - 4 +2B - 4 + B.
77 = 5B - 8.
77 + 8 = 5B.
85 = 5B
B = 85/5
B=17 ft
You need a right triangle correct. If you used a graph and put the points (5,12) & (11,12) it would make sense to have the next point --this(11,4)
3/7 is the answer for this question
