Evaluate the expression for

A=4 B=2

3(a+7)-4b

1 answer

First, substitute the given values for A and B into the expression:

3(4+7)-4(2)

Next, perform the calculations inside the parentheses:

3(11)-4(2)

Multiply 3 by 11:

33-4(2)

Multiply 4 by 2:

33-8

Finally, subtract 8 from 33:

25

Therefore, the expression 3(a+7)-4b with A=4 and B=2 evaluates to 25.
