To expand the expression \( \frac{7}{4}(8h + 3) \), you distribute \( \frac{7}{4} \) to both terms inside the parentheses:
\[ \frac{7}{4}(8h) + \frac{7}{4}(3) \]
Now, calculate each term:
-
For the first term: \[ \frac{7}{4} \cdot 8h = \frac{7 \cdot 8h}{4} = \frac{56h}{4} = 14h \]
-
For the second term: \[ \frac{7}{4} \cdot 3 = \frac{21}{4} \]
Combining both results, we get: \[ 14h + \frac{21}{4} \]
Thus, the expanded expression is: \[ 14h + \frac{21}{4} \]
