Answer:
c. is incorrect
Step-by-step explanation:
2 + 3(x + 3) + x
<em>use the Distributive property a(b + c) = ab + ac</em>
= 2 + 3x + 9 + x <em>a. is correct</em>
<em>use the Commutative property of addition: a + b = b + a</em>
= 2 + 9 + 3x + x <em>addition</em>
= (2 + 9) + 3x + x
= 11 + 3x + x <em>b. is correct</em>
<em>use the </em><em>Distributive property</em><em> a(b + c) = ab + ac</em><em> </em>
<em>not Associative property (a + b) + c = a + (b + c)</em>
= 11 + (3 + 1)x <em>c. is incorrect</em>
= 11 + 4x
<em>use the Commutative property of addition: a + b = b + a</em>
= 4x + 11
