Sedbober [7]

Answer:

d. false, (3 × 6) + 4 < 8 + 4 + 32

Step-by-step explanation:

We want to determine whether, (3 × 6) + 4 = 8 + 4 + 32 is a true or false statement.

Let us first of all simplify the LHS of given expresion to get:

(3 × 6) + 4 = 18+4=22

The RHS is 8+4+32=12+32=44.

We can see that the LHS is less than RHS.

The correct answer is

d. false, (3 × 6) + 4 < 8 + 4 + 32
