A credible source is one that is reliable (accurate data and representations) and usually from government organizations/websites, peer-reviewed journals, or university documents/papers.

An algebraic expression deals with variables and is much more complex than a numerical expression [only includes numbers].

An example of an algebraic expression is 14x -32. 

An example of a numerical expression 14 + 32.

Area of a triangle = 1/2(b*h) where b = base of the triangle & h = height of the triangle.

Let's see:

y sigma x X ^ 

= unknown variable add/sum multiply unknown variable exponent/to the power.

= Uknown variable summed up multiplied by another unknown variable with power

= Unknown variable cross multiplied by another unknown variable with power.

= The sum of the powers of the unknown variables are great.

= Unknown variables crossed together unleash tremendous power.

= We cannot underestimate the power of the unknown.

= The unknown is unpredictable.

I assume 61/2 divided by 31/3 is the question:

If so, 61/2 X 3/31 (Skip first term, change from division to multiplication, and flip the second term)

61*3 / 62 = 183/62 = 2.9516129032258065.

F(x)=x²-10 and G(x)=2-x

(f/g)(x) = x^2-10 / (2 - x)

(f/g)(-6) = (-6^2) - 10 / (2 - (-6))

= 36 - 10 / (8)

= 26/8.*

Another method as follows:

F(x)=x²-10 and G(x)=2-x

f(-6) = (-6)^2 - 10 = 36 - 10 = 26

g(-6) = 2 - (-6) = 8

f(-6) / g(-6) = 26/8.*

*(f/g)(-6) = f(-6)/g(-6)

All of them have something to do with symbols and using them to represent different variables.

√(64²-50²)

= sqrt(1,596)

y - 2 = 2(x + 3) --> We want a form: y = mx + b with m = slope and b = y-intercept

y - 2 = 2x + 6 -->

y = 2x + 8.
