All you have to do is combine like terms here...all the x's and then all the constants. 2.3x + 2x -.2x = 4.1x; 14 + 15 = 29, so the perimeter is 4.1x + 29, A above.
After removing the outliers, the new total of student heights is
68*50 -82 -86 = 3232
so the new mean is
3232/48 = 67.33
<span>(7x+3)-(2x+1)
=</span><span>7x + 3 - 2x - 1
= 5x + 2</span>
I think the answer is 12.9
The prime factor of the 576 is
and the prime factor of the 64 is
. And the expression
is equal to 3.
