If you plug the x and y value's and the last one is the answer.
4(1)+3(4)=4+12=16
7(1)+6(4)=7+24=31
Answer:
Step-by-step explanation:
If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:
3x - 7 = 5(x - 5) and
3x - 7 = 5x - 25 and
18 = 2x so
x = 9. Now we sub that into the expression for AB (or DE since they're the same length):
3(9) - 7 = 20
Both AB and DE measure 20 units.
Answer:
2/52 or 1/26
Step-by-step explanation:
So triangle has 3 sides
represent them as x,y,z
so lets say x=shortest side
y=2nd side
z=longest side
x is 1/2 of the second side
x=1/2(y)
shortest side is 1/3 of the longset side
x=1/3(z)
how does the triangle compart the longest side (z)
x+y+z=perimiter
solve to subsitute and convert all values to z
x=1/2y
2x=y
2(1/3z)=y
2/3(z)=y
and x=1/3(z)
therefor, subsitute so that there are only z terms
1/3(z)+2/3(z)+z=perimiter
add like terms
3/3(z)+z=p
z+z=p
2z=p
the peimiter is 2 times of the longest side
