Answer 14

Which algebraic expression is equivalent to the expression below?

9(4x + 8) - 6
36x + 18
36x + 72
36x + 2
36x + 66

Answer 15

Have you tried working this out on your own? Distribute the 9 to 4x + 8, then subtract the 6. Follow your order of operations.

Answer 16

yes but it hard and if i don't get this done i'll fail and my dad will spank me

Answer 17

What did you get for your answer?

Answer 18

Answer 20

can u teach me what it is i don't know and i don't want to fail

Answer 21

Sure.

Follow your order of operations, PEMDAS (Parentheses, Exponent, Multiply/Divide, Add/Subtract).

Starting with parantheses, we see that we cannot simplify (4x+8) any further. The next thing on the list that we can do is multiply. Whenever we multiply across an expression with two terms, we must distribute.
AKA:
9(4x+8) = 36x+72
We multiply each term by that number (in this case 9).

But we're not done yet. We still have that 6 that we must subtract.

36x + 72 - 6 = 36x + 66
