SO to find percent
just multiply the number by the percent
Remeber the percent means x/100
SO in this case 20/100 or 1/5
So you can just multiply 1/5*8 and get 1 3/5.
If you convert 3/5 into a decimal
3 divided by 5
that is .6
SO add them up
1+0.6= $1.60
(2 - 7z)(2 + 7z)
= (2)^2 - (7z)^2
= 4 - 49z^2
