1a) 1141/660
3/5 + 6/11 +7/12
find the LCM of the denominators
the LCM of 5,11,12 is 660
after finding the LCM divide it with the denominator.
after dividing 660 by 5 i get 132. So i need to multiply it with 3. Now, i got 396. Do the same with the rest of the numbers.
u will get smth like this: 396+360+385/660
and the final answer will be1141/660.

Given:
To Find?
Solution:
Using formula:
Where,
→ 7719 = x × 83
→ x = 7719/83
→ x = 93 cm
Hence,
area = 18x² + 63x + 55 square units
Second-degree trinomial.
Step-by-step explanation:
area = (3x+5)(6x+11) = 18x² + 63x + 55 square units
