Answer:
25 K³ - 35k²+ 50 K - 40
===========================================
Step-by-step explanation:
Given that :
(-5k + 5)(-5k² + 2k - 8)
= -5K (-5k² + 2k - 8) + 5 (-5k² + 2k - 8)
= 25 K³ - 10k² + 40 K - 25 K² + 10 K - 40
= 25 K³ - 35k²+ 50 K - 40
<u>So, the product = 25 K³ - 35k²+ 50 K - 40</u>

Answer:
8 statues, with a bit of paint left over
Step-by-step explanation:
Divide the 8/9 liter of paint by the quantity of paint needed per statue, to obtain the number of statues Erin can paint:
8/9 liter 8 10
------------------------- = ----- * ----- statues = 80/9 statues.
1/10 liter / statue 9 1
80/9 statues comes out to 8 8/9 statues. 8 statues can be painted, but Erin will either have to settle for partially painting one more statue or not using up the last remaining bit of paint.
