Question

Find the value of each expression. 6b2 – 5 if b = 3

Answer 1

Answer:

31

Step-by-step explanation:

Hello$!$

I think the "6b2" part is confusing you. Remember if the digits are next to each other, it represents multiplication.

The simplified expression with b = 3:

6 × 3 × 2 - 5

Now, we apply PEMDAS:

36 - 5

That gives:

31.

Thus, the final value of the expression is $\boxed{\boxed{31}}$.

Hope this helps!

Answer 2

The answer should be 31, if I’m doing this correctly.
6(3)2-5 (multiply 6 and 3, you get 18)
18(2)-5 (multiply 18 and 2, you get 36)
36-5 (subtract 36 and 5)
31
