595
Step-by-step explanation:
Answer: B = $ 3.25
S = $ 9.75
P = $ 19.5
Step-by-step explanation: Please find the attached file for the solution
M=(1+7/2,2+10/2)=(4,6)
mf=squr(4-7)^2+(6-10)^2=5
Using a^2+b^2=c^2
7^2 +7^2=c^2
49+49= c^2
c^2= 98
c= the square root of 98
I think the answer would just be 12a because -9a? And +9a? Would cancel out and the -10 and +10 would cancel out so all that is left is the 12a
