Which expression is equivalent to 6u + 9u? Choices: (A)u + 15 (B)u^15 (C)15u (D)16u

Combine Like Terms: We need to combine like terms, which in this case are 6u and 9u. To combine like terms, we simply add their coefficients. Calculation: 6u + 9u = (6 + 9)u = 15uCompare with Choices: Now we compare our result with the given choices to find the equivalent expression. (A) u + 15 is not correct because it suggests adding u and 15, not multiplying them. (B) u^15 is not correct because it suggests raising u to the 15th power, not multiplying u by 15. (C) 15u is the correct choice because it is the result of adding the coefficients of u from the original expression. (D) 16u is not correct because it suggests the coefficient of u is 16, which is not the case.

Q. Which expression is equivalent to

6u + 9u

\newline

Choices:

\newline

(A)

u + 15

\newline

(B)

u^{15}

\newline

(C)

15u

\newline

(D)

16u

Combine Like Terms: We need to combine like terms, which in this case are $6u$ and $9u$ . To combine like terms, we simply add their coefficients. $\newline$ Calculation: $6u + 9u = (6 + 9)u = 15u$
Compare with Choices: Now we compare our result with the given choices to find the equivalent expression. $\newline$ (A) $u + 15$ is not correct because it suggests adding $u$ and $15$ , not multiplying them. $\newline$ (B) $u^{15}$ is not correct because it suggests raising $u$ to the $15$ th power, not multiplying $u$ by $15$ . $\newline$ (C) $15u$ is the correct choice 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 coefficient of $u$ is $u$ $2$ , which is not the case.
