Answer:
The sides of a triangle are 8 cm, 11 cm and 13 cm. What is its area? 9. The sides of a triangle are 15 cm, 17 cm and 8 cm. What is its area? 10. The sides of a triangle are in the ratio of 3 : 4 : 5. If its perimeter is 36 cm, then what is its area? 1. D 2. B 3. A 4. B 5. C 6. A 7. C 8. A 9. C 10. B
Step-by-step explanation:
To find the critical number of that function we have to find the derivative and set it equal to 0 and solve for x. The derivative of the function is f'(x)=-10x+2. If we set it equal to 0 and solve, we have x = -2/-10 which simplifies to x = 1/5.
If you are asking which is bigger then it is 4/6
<u>1/3; 2/7; 2/9</u>
Lets find least common multiple
The least common multiple is 63
1/3 --> 21/63
2/7 --> 18/63
2/9 --> 14/63
As you can see I am correct, but I found the LCM by multiplying 1/3 by 21 to get to 63 and the numerator as well
