Use the distributive to evaluate each expression
4(12 + 3)

4(12 + 3) = 48 + 12 = 60

Step-by-step explanation: We will use the distributive property to evaluate the expression, 4(12 + 3)

Simply do this by multiplying the number outside of the parenthesis by each number inside of the parenthesis.

4(12 + 3)

4 x 12 = 48 and 4 x 3 = 12

(48 + 12)

Now, add both numbers inside the parenthesis.

(48 + 12 = 60) or 60.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
