To multiply the binomials \((3x + 7)(2x - 5)\) using the FOIL method, we will calculate the product using the following steps:

FOIL stands for First, Outside, Inside, Last.

  1. First: Multiply the first terms in each binomial. \[ 3x \cdot 2x = 6x^2 \]

  2. Outside: Multiply the outside terms in the product. \[ 3x \cdot (-5) = -15x \]

  3. Inside: Multiply the inside terms. \[ 7 \cdot 2x = 14x \]

  4. Last: Multiply the last terms in each binomial. \[ 7 \cdot (-5) = -35 \]

Now, combine all these results: \[ 6x^2 - 15x + 14x - 35 \]

Combine the like terms \(-15x\) and \(14x\): \[ 6x^2 - 1x - 35 \]

So the answer in the required format is:

Question Blank 1 of 4: \(6\)
Question Blank 2 of 4: \(-1\)
Question Blank 3 of 4: \(x\)
Question Blank 4 of 4: \(-35\)

Final result: \[ 6x^2 - 1x - 35 \]
