Answer:

Step-by-step explanation:
So, for 60 square feet they charge = 287
So, for 1 square foot they charge = 
If they charge the installation fee this becomes = 
We can write an equation to calculate cost by using this 
Where x is the amount of square foot
Answer:
-7
Step-by-step explanation:
given f(x)=4x+k
therfore, f(2)=4*2+k
we know that f(2) =1
so, 4*2+k=1
8+k=1
k=1-8
k=-7
CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
