Answer:
B. 9k^2 + 5k - 1
Step-by-step explanation:
4k^2 + 5k - 3 + 5k^2 + 2
= 4k^2 + 5k^2 + 5k - 3 + 2
= 9k^2 + 5k - 1
Based on the fact that you are allowed to multiply as many 2's and/ or as many 5's as you want, the last digit of your result can be either a 2, 5 or 0.
<h3>What is the last digit of your result?</h3>
If you multiplied a 5 number with another 5 number, you will either get a 0 as the last digit or a 5 as the last digit:
5 x 5 = 25
5 x 10 = 50
5 x 15 = 75
5 x 25 = 125
If you multiply a 5 with a 2, you result would always end in 0:
5 x 2 = 10
5 x 4 = 20
5 x 6 = 30
If you multiply a 2 with another 2, the result would be a 2:
2 x 2 = 4
2 x 4 = 8
2 x 6 = 12
