Answer:
Let's say that x is sam's age and y is Amy's age
x=y-4
and five years ago:
x-5=(y-5)/2
y-4-5=(y-5)/2
2y-18=y-5
y=13
x=9
then:
sam's age is 9 and Amy's age is 13
The difference of two squares. The number which, when multiplied together three times yields the original number.
Answer: B: 41, C: 68, D: 71.
Step-by-step explanation: A triangle's angles have to add up to 180 degrees for it to be considered a triangle. If you were to add up 71, 41, and 68, then it would equal 180 degrees. This means that out of all the other measurements, these are the three possible angle measures that can be used to make a triangle.
(I figured this out by taking 3 random sides from the list there and adding them up to see if they equal 180.)
In this pattern , the numbers are doubling..
2,4,6,8,10...
Answer:
the answer should be 
or 11^5
Explanation:
Since there are five 11 in the equation, the answer should be or 11^5
You shouldn't write 161051 as the answer because it is NOT a exponent.
