The expression for the total number of miles he drove in the two weeks is m + 153
<h3>How to determine the expression for the total number of miles he drove in the two weeks?</h3>
The given parameters are
Last week = m miles
This week = 153 miles
The expression for the total number of miles he drove in the two weeks is
Expression = Last week + This week
This gives
Expression = m + 153

(x+5)(x-5) , You use difference of two squares to do this. Remember that if the sign in the equation was (+) then you wouldn’t be able to continue factoring. You can only factor equations like these if there is a subtraction sign.
H=-4.9t^2+25t
0=t(-4.9t+25)
T=25÷4.9
T= approx 5.1 which is closes to 5.0 So answer will be 5.0
