You can distribute the q to both terms to get
[tex] q(2a+1) = q\cdot 2a + q\cdot 1 = 2aq+q [/tex]
Answer:
2aq +q is an equivalent expression for q(2a+1)
Step-by-step explanation:
an equivalent expression to q(2a+1)

q times 2a = 2aq
q times 1 is q
Now we combine both term
q(2a+1)= 2aq + q
So 2aq +q is an equivalent expression for q(2a+1)
