19.1
Step-by-step explanation:
Answer:
A = 33 1/3 ft²
It's the one you picked lol
Answer:
2=k^1/x
3=k^1/y
12=k^1/z.......we get...
(atq)------k^1/x=k^1/y=k^1/z
(*a^m=b^m......b=a)
~1/x=1/y=1/z
1/z=1/y+1/x×2
(12=3+2×2)
1/z=1/y+2/x.....proved
Divide 252 by 21.
21 times 12 = 252
12 is 9 units shorter than 21.
so the answer is 12 inches by 21 inches
you work backwards from the area
area = width times length
a = wl
we know w is 9 units shorter than the length
so now we have the equation 252=(l-9) times l
plug in 21 for l and then solve there is your answer.
