Answer:
x=3, y=76
Step-by-step explanation:
You set them equal because you plug in "y" as 22x+10 into "y=20x+16"
22x+10=20x+16
2x=6
x=3
20(3)+16=76
Hello,
A(x)=x²-x-72 (m²)
L=(x+8) (cm)= (x+8)/100 (m)
We suppose here x≠-8
(in reality x²-x-72>0 ==>x<-8 or x>9
but x+8>0 ==> x>-8
then
only x>9 are solutions)
W=A(x)/ ((x+8)/100 )=100*(x²-x-72)/(x+8)= 100*(x-9)(x+8)/(x+8)=100*(x-9)
