(a+5)(a+2) = a^2 + 7a + 10
look at what adds to make 7 and multiplies to make 10
as you know one is 5, the other is 2 and 5 + 2 = 7 so both positive
(a+2)

-----.135as a fraction

Mrac [35]

This has to do with place value.
0.135.....the last digit (5) is in the thousandths place....so put it over 1000.
135/1000 reduces to 27/200
