Answer:
<em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r² </em>
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)
2r²(6r³ + 14r² - 30r + 14) = <em>12 </em><em> + 28 </em><em> - 60 r³ + 28 r²</em>
Answer:12 = 12.
x 6 = 12.
x 4 = 12.
x 3=12
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
4 x 12 = 6 x 4 x n
Which gives
48 = 24n
48/ 24 = n
so n = 2
After simplifying the expression, we get 18a^6b^9
Which tells us choice C is correct.
