Answer: (10 2/3, 5)
Step-by-step explanation:
Answer:
i have never seen 2 pretty best friends. can some one prove me wrong.
L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=3w-4
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64
Answer:
x = 12.
Step-by-step explanation:
If P(5,4),Q(8,10) and R(x,18) are collinear
then the slope of PQ equals the slope of QR
hence:
(10 - 4)/(8 - 5) = (18 - 10)/(x - 8)
6/3= 8/(x - 8)
2 = 8/(x - 8)
multiplying both sides by (x - 8) gives:
2(x - 8) = 8
2x - 16 = 8
2x = 8 + 16 = 24
hence x = 12
