(2q^(5)+7q)+(5q^(5)+3q^(3)) Which of the following expressions is equivalent to the given expression? Choose 1 answer: (A) q(7q^(4)+10) (B) q(7q^(4)+10q^(2)) (C) q(2q^(4)+12q^(3)+3q^(2)) (D) q(7q^(4)+3q^(2)+7)

Combine like terms: Combine like terms in the expression (2q^(5)+7q)+(5q^(5)+3q^(3)). To combine like terms, we add the coefficients of the terms with the same exponent. The terms 2q^(5) and 5q^(5) are like terms, so we add their coefficients: 2 + 5 = 7. The term 7q has no like term to combine with, so it remains as is. The term 3q^(3) has no like term to combine with, so it remains as is. The combined expression is 7q^(5) + 3q^(3) + 7q.Add coefficients of like terms: Look at the answer choices to determine which one matches the combined expression. (A) q(7q^(4)+10) does not match because it does not have a q^(5) term or a q^(3) term. (B) q(7q^(4)+10q^(2)) does not match because it does not have a q^(5) term or a q^(3) term. (C) q(2q^(4)+12q^(3)+3q^(2)) does not match because the coefficients of q^(5) and q^(3) terms do not match the combined expression. (D) q(7q^(4)+3q^(2)+7) does not match because it does not have a q^(5) term or a q^(3) term, and the factorization is incorrect. None of the answer choices directly match the combined expression 7q^(5) + 3q^(3) + 7q.Identify terms with no like terms: Realize that there is a mistake in the previous step because the combined expression should be correctly matched with one of the answer choices. We need to re-evaluate the answer choices with the correct combined expression 7q^(5) + 3q^(3) + 7q.

Combine like terms: Combine like terms in the expression $(2q^{5}+7q)+(5q^{5}+3q^{3})$ . $\newline$ To combine like terms, we add the coefficients of the terms with the same exponent. $\newline$ The terms $2q^{5}$ and $5q^{5}$ are like terms, so we add their coefficients: $2 + 5 = 7$ . $\newline$ The term $7q$ has no like term to combine with, so it remains as is. $\newline$ The term $3q^{3}$ has no like term to combine with, so it remains as is. $\newline$ The combined expression is $7q^{5} + 3q^{3} + 7q$ .
Add coefficients of like terms: Look at the answer choices to determine which one matches the combined expression. $\newline$ (A) $q(7q^{4}+10)$ does not match because it does not have a $q^{5}$ term or a $q^{3}$ term. $\newline$ (B) $q(7q^{4}+10q^{2})$ does not match because it does not have a $q^{5}$ term or a $q^{3}$ term. $\newline$ (C) $q(2q^{4}+12q^{3}+3q^{2})$ does not match because the coefficients of $q^{5}$ and $q^{3}$ terms do not match the combined expression. $\newline$ (D) $q(7q^{4}+3q^{2}+7)$ does not match because it does not have a $q^{5}$ term or a $q^{3}$ term, and the factorization is incorrect. $\newline$ None of the answer choices directly match the combined expression $q^{5}$ $2$ .
Identify terms with no like terms: Realize that there is a mistake in the previous step because the combined expression should be correctly matched with one of the answer choices. $\newline$ We need to re-evaluate the answer choices with the correct combined expression $7q^{5} + 3q^{3} + 7q$ .
