If you don't include the outlier (50) then it is 79.7
She can arrange them in the following;
1 row of 36
2 rows of 18 (doesnt count because it says other and this has already been mentioned)
3 rows of 12
4 rows of 9 (doesnt count because it says other and this has already been mentioned)
6 rows of 6
An inch = 2.54 Centimeters. So take 34.5 × 2.54 and you will get 87.63 centimeters.

(b^2)^4 = b^8
answer is 4 (2nd choice)
Not sure if my picture answer make sense so, when you have a^2 and b^2 to find c^2 u add then and then square root it to get c. e.g 81^2 + 108^2 = 18225 then u square root it and get 135. when u are given the hypotenuse (which is always c^2) u take that away from the a^2/b^2 and square root. e.g 8^2-4^2 which is 48 which can’t be square rooted so just leave as root48
