Expand and simplify4(q−4)−4(q−7)

Step 1: Distribute the 4 in the first term and the -4 in the second term.

4 * q = 4q 4 * -4 = -16 -4 * q = -4q -4 * -7 = 28

So, the expression becomes: 4q - 16 - 4q + 28

Step 2: Combine like terms.

4q - 4q = 0 -16 + 28 = 12

So, the simplified expression is: 0 + 12 = 12
