(x+6)(x+2)=60
expand
x^2+6x+2x+12=60
x^2+8x+12=60
minus 60 both sides
x^2+8x-48=0
factor
what multiplies to -48 and adds to 8
-4 and 12
(x-4)(x+12)=0
set each to zero
x-4=0
x=4
x+12=0
x=-12
x=4 or -12
solutions are x=-12 and 4

A=3.14r^2
A=3.14 x 10^2
A=3.14x100

462
x 8
-------
3704
multiply each digit of 462 by 8. you get 3704.

so we move the decimal 2 places to the left in 3704, the answer
and we get 37.04
