Answer:
8n+12=36, triplets are 8 years old
Step-by-step explanation:
total age is 36
one of them is 12 years old so -> 36-12 = 24
three triplets so 24/3 = 8
there are three 8 years olds and one 12 year old. n = 3
5.5x1000=5,500m
5,500x100=550,000cm
OR
5.5x100,000
2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.
So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2
The new exponent is 2 because -3-(-5) is equal to 2.
Step-by-step explanation:
let width =x
length=x+14
....
perimeter=96=2*(L+W)
96=2*(X+X+14)
96=4x+28
96-28=4x
68=4x
/4
68/4=x
17=x the width
length = 17+14=31m
....
Check
17+17+31+31=96
