Step-by-step explanation:
this month-100 percent
then previous month 100-20=80 percent
so
if 48=100percent
then x=80percent
x=(80×48)/100
x=38.4 ≈ 38 pairs if shoes
Answer:
4x^2+10x-2=0
Step-by-step explanation:
So the total area of mirror: 2*3 = 6 ft sq
8-6 = 2 ft sq is the area of the frame
x is the thickness of the frame
so we have (2*x)*2+(3*x)*2+x*x*4= 2
4x+6x+4x^2=2
-> 4x^2+10x-2=0
Answer:
