Which expression is equivalent to 5u + 4u? Choices: (A)u + 9 (B)u^9 (C)9u (D)8u

Combine like terms: We are asked to find an expression equivalent to the sum of 5u and 4u. To do this, we combine like terms by adding the coefficients of u. Calculation: 5u + 4u = (5 + 4)u = 9uCompare with choices: Now we compare our result with the given choices to find the equivalent expression. (A) u + 9 is not correct because it suggests adding u and 9, not multiplying them. (B) u^9 is not correct because it suggests raising u to the 9th power, not multiplying u by 9. (C) 9u is correct because it is the result of adding the coefficients of u from the original expression. (D) 8u is not correct because it suggests the sum of the coefficients is 8, not 9.

5u + 4u

\newline

Choices:

\newline

(A)

u + 9

\newline

(B)

u^9

\newline

(C)

9u

\newline

(D)

8u

Combine like terms: We are asked to find an expression equivalent to the sum of $5u$ and $4u$ . To do this, we combine like terms by adding the coefficients of $u$ . $\newline$ Calculation: $5u + 4u = (5 + 4)u = 9u$
Compare with choices: Now we compare our result with the given choices to find the equivalent expression. $\newline$ (A) $u + 9$ is not correct because it suggests adding $u$ and $9$ , not multiplying them. $\newline$ (B) $u^9$ is not correct because it suggests raising $u$ to the $9$ th power, not multiplying $u$ by $9$ . $\newline$ (C) $9u$ is correct because it is the result of adding the coefficients of $u$ from the original expression. $\newline$ (D) $u$ $0$ is not correct because it suggests the sum of the coefficients is $u$ $1$ , not $9$ .
