What value correctly fills in the blank so that the expressions are equivalent?

32 + 72 = _ (4+9)

A. 12
B. 8
C. 4
D. 13

1 answer

To find the value that correctly fills in the blank in the equation \( 32 + 72 = _ (4 + 9) \), we first need to simplify both sides of the equation.

  1. Calculate the left-hand side: \[ 32 + 72 = 104 \]

  2. Next, simplify the right-hand side, focusing on \( 4 + 9 \): \[ 4 + 9 = 13 \]

  3. Now, we can rewrite the equation using the value we've calculated: \[ 104 = _ \times 13 \]

  4. To find the value of the blank (let's denote it as \( x \)), we can solve for \( x \): \[ x \times 13 = 104 \] \[ x = \frac{104}{13} \]

  5. Performing the division: \[ \frac{104}{13} = 8 \]

Thus, the value that correctly fills in the blank is \( \boxed{8} \).
