No, 50 is not a perfect square. A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational. When you divide 50 so that the quotient equals the divisor, you will get an irrational number. Therefore, 50 is not a perfect square.
(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.
Answer:
Step-by-step explanation:
Jen: (1+2/3)x4 to find average (multiply by 4 to get 1 hour)
Jen's ave. is 3+2/3 mph
Max: (1.5)x5= average
Max's is 9 mph
Max is faster.
3 (m + 5 + 9m)
Two expressions that are e<span>quivalent to the given expression are:
3m + 15 + 27m
or
30m + 15
you get both expressions by multiplying the original expression
the second expression is obtained by adding the like terms</span>
