Step-by-step explanation:
Add 9 to both sides of the equation.
if you want to create a trinomial square on the left, find value that is equal to the square of half of b
Add the term to each side of the equation
SIMPLIFY >:(
How to Simplify it:
-Raise the -2 to the power of 2
and ten simplify 9 + (-2)^2 :
--Raise -2 to the power of 2 and then add 9 and 4
Factor the perfect trinomial square into (x - 2)^2
Solve the equation for x
How to do it:
-Take the square root of each side of the equation to set up the solution for x
--Then remove the perfect root factor, x - 2 under the radical to solve for x
---Remove parenthesis
----add 2 to both sides of the equation.
the final answer could be shown in different ways,but the exact form is x=±√13+2
In decimal form its x=5.60555127…,−1.60555127…
--this took me like 7 minutes to do im no geek tho lol
Remmeber that an octagon is a polygon formed by chain of 8 straight line segments.
The first valid name for a polygon of eight sides is octagon (from greek oktagonon, which means eight angles)
The second valid name for a polygon of eight sides is eight-sided polygon.
The third valid name of a polygon of eight sides is 8-gon. After 6 sides, mathematicians usually refer to these polygons as n-gons, so an eight-sided polygon will be an 8-gon.
We can conclude that the three valid names for an octagon are: octagon, eight-sided polygon, and 8-gon.

Answer:
M(B(h))=78.18025h
Step-by-step explanation:
First we have the following equations:
L(h) = 28.75h eq. 1
B(L) = 1.78L eq. 2
M(B) = 1.43B eq. 3
To find the selling price based on the estimated number of hours, we need to start replacing equation 1 in equation 2 as:
B(L) = 1.78*B
B(L(h)) = 1.78*(28.75h)
B(L(h)) = B(h) = 51.175h eq. 4
Finally, if we weplace equation 4 in equation 3, we get:
M(B) = 1.43B
M(B(h)) = 1.43*(51.175h)
M(B(h)) = 73.18025h
So, the composite function that can be used to find the selling price for the labor portion of a bid based on the estimated number of hours is:
M(B(h)) = 73.18025h
