There are 12 inches in 1 foot. This is equivalent to 60 inches in 5 feet. Which proportions can be used to represent this? Check all that apply. StartFraction 12 over 1 EndFraction = StartFraction 5 over 60 EndFraction StartFraction 12 over 1 EndFraction = StartFraction 60 over 5 EndFraction StartFraction 1 over 12 EndFraction = StartFraction 5 over 60 EndFraction StartFraction 1 over 12 EndFraction = StartFraction 60 over 5 EndFraction

answer: 12/1=60/5. 1/2=5/60

Step-by-step explanation:

Just took the test

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
