Full solution

Q. Select the expressions that are equivalent to

4h + 5h

.

\newline

Multi-select Choices:

\newline

(A)

3h + 7h

\newline

(B)

h \times 9

\newline

(C)

h + 9

\newline

(D)

9h

Combine like terms: Combine like terms in the expression $4h + 5h$ . $\newline$ Calculation: $4h + 5h = 9h$ .
Compare with choices: Compare the result with each choice: $\newline$ (A) $3h + 7h = 10h$ (not equal to $9h$ ), $\newline$ (B) $h \times 9 = 9h$ (equal to $9h$ ), $\newline$ (C) $h + 9$ (not equal to $9h$ ), $\newline$ (D) $9h$ (equal to $9h$ ).
Select correct choices: Select the correct choices based on the comparison: $\newline$ Choices (B) and (D) are equivalent to $9h$ .
