Answer:
A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square. Obtain the digital root of the number. The digital root essentially is the sum of all of the digits.

Answer:
2x^2+2x
Step-by-step explanation:
The large squares are x^2.
The rectangles are x
The small squares are 1
We have 2 large squares = 2x^2
and 2 rectangles = 2x
2x^2+2x
-9x - 2
-9 (7) - 2
-63 - 2
-65
This is true because 2/5 = 4/10
If u gave 1/10 of a pizza to 6 friends then you would have given them 6/10 of your pizza and have 4/10 left over because 4/10 + 6/10 = 10/10 or 1
Hope this helped :)
