168

So you take the 144 divide 12(the dozen) so we could find how much 1 cost, it was 12. You added 2 more books so we add(12x2)+(144). That equals to 168

Hope this helps!

Find the distance and midpoint between the points (7, 3) and (-2,-5).

pochemuha

(7,3)
(-2,-5)

Distance:-

$\\ \rm\Rrightarrow \sqrt{(7+2)^2+(3+5)^2}$

$\\ \rm\Rrightarrow \sqrt{9^2+8^2}$

$\\ \rm\Rrightarrow \sqrt{81+64}]/tex][tex]\\ \rm\Rrightarrow \sqrt{145}$

$\\ \rm\Rrightarrow 12(approx)$

Midpoint

$\\ \rm\Rrightarrow \left(\dfrac{7-2}{2},\dfrac{3-5}{2}\right)$

$\\ \rm\Rrightarrow \left(\dfrac{5}{2},\dfrac{-2}{2}\right)$

$\\ \rm\Rrightarrow \left(\dfrac{5}{2},-1\right)$
