Step-by-step explanation:

The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

$\frac{5}{7}+ \frac{10}{1} \\The \ LCM \ is \ 7\\\\= \frac{5(1)+10(7)}{7}\\\\= \frac{5+70}{7}\\\\= \frac{75}{7} \\\\= 10 \frac{5}{7}$

Hence the expression written in equivalent form of common denominator is $\frac{5 + 70}{7}$

The sum is $10 \frac{5}{7}$

Answer:

Step-by-step explanation:

Well you can get rid of c and d since 9^2 = 81. so 74 is less than 81 so it's definitely less than 9. Now, we know it's between 8 and 9. try multiplying 8.5 x 8.5 = 72.25. So our ranges are

A) 64 - 72.25

B) 72.25 - 81.

74 falls between 72.25 - 81. So it'll be B
