It had to be B
because 6 is subtracted by the number n and the only one that has n-6/ 6-n is B
The perimeter of each frame would be 24 inches.
24 x 5 = 120
So the total length around all of the frames would be 120 inches.
Answer:
5 + a
A: ---------
a - 1
Step-by-step explanation:
3+x 3 + a + 2
f(x) = ---------- becomes f(a + 2) = ------------------
x-3 a + 2 - 3
5 + a
when a + 2 is substituted for x. This last result simplifies to ------------
a - 1
which matches Answer A.
hii
Step-by-step explanation:
length-10x
width-x
perimeter-2(l+b)
66=2(10x+x)
66-2=10x+x
64=11x
x=11/64
lenght-11
width-64
