For b it's 39 because you multiply 5 and 7 giving you 35 then add 4 Wich equals 39. I might be incorrect. check it out.
IT IS A HOPE THIS HELPS!!!

<span>4k – 6 = -2k – 16 – 2
</span>4k+2k = – 16 – 2+6
6k=-12
k=-2
Hope this helps
The volume of a sphere is (4πr^3)/3 and since r=d/2, volume of a given sphere with respect to its diameter is:
V=(4πd^3)/24
V=(πd^3)/6 in this case d=8.65 so
V≈338.88 in^3 (to the nearest hundredth)
<span>52 rounded to the nearest hundred </span>= 100
cause 52 > 50
hope it helps
