Answer:
the two numbers are 151 and 66
Step-by-step explanation:
x+y =217
x-y = 85
add the two equations
x+y =217
x-y = 85
-------------
2x = 302
divide by 2
2x/2 = 302/2
x = 151
now find y
x+y =217
151+y =217
subtract 151 from each side
y = 217-151
y =66
I think it would be (D. 88)

Answer:
13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
x +3x +3x = 91
x = 91/7 = 13
3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm.
