Answer:

31

Step-by-step explanation:

Hello!

I think the "<em>6b2" </em>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!

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

marusya05 [52]
The perimeter of a figure is the total distance around the edge of the figure. The area of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square foot or a square inch. I don't really know the rest but I did the first two lol

alexdok [17]

Answer:

£210

Step-by-step explanation:

Given that :

Visa cost = £2300

7% charge of visa price = (0.07 * £2300) = £161

Total cost = £(161 + 2300) = £2461

Amount to be saved per month = £2461 / 12 = £205.08333

= £210 (nearest £10)
