It is 3 1/8 because 9.2 is a decimal and a fraction is 3 1/8 and a mixed fraction is 3 7/8
Ok so this is a difference of 2 perfect squares
1=1^2
49c^2=(7c)^2
to factor you remember
a^2-b^2=(a+b)(a-b) so
1^2-(7c)^2=(1+7c)(1-7c)
Slope = (9-3)/(5-2) = 6/3 = 2
answer
<span>A) 2 </span>
M is equal to 6 because 6 times 2 would equal 12
An hour has 60 minutes so 1/40 of an hour is:
(1/40)(60) = 60/40 = 6/4 = 3/2 = 1.5
so 1/40 of an hour is a minute and a half
