Answer:
Step-by-step explanation:
7h+3=7(2+h)-11
7h+3=14+7h-11
7h+3=7h+3
The answer is 0 or no solution since they cancel each other out.
Your answer is the first option -4<x<_4
Answer:
Step-by-step explanation:
I believe the only way to solve this is by Heron's Formula.
Add up all the sides and divide by 2 to get the semi-perimeter:
113+100+86 = 299
299/2 = 149.5
Now fill in the rest, which looks like this:

where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:

which simplifies to

which simplifies further to

which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).
Sin+cos=90
49+cos=90
cos=41

Answer: 22.5</h3>
Work Shown:
450 calories = 20 ounces
450/20 calories = 20/20 ounces ..... divide both sides by 20
22.5 calories = 1 ounce
