I believe the answer is b= -5
2x-7 * x
----------- =. 100^2= 10000
2
2x^2-7/2= x^2-7/2
x^2-7/2=10000
x^2 = 20007/7
2. Y=x/5
3. G= f/h
5. B= m/f
6. D=b/8
I hope these are right for you
If it has 3 sides then it's a triangle.
Using the formula
where

and a=5 b=5 c=8
∴
To calculate for mass, simply multiply molar weight (MW)
and number of mols. The molar weight (MW) is in units of mg / mmol. Therefore
the mass is:
mass = (158 mg / mmol) (0.25 mmol)
mass = 39.5 mg
Answer:
39.5
