We want to see which offer is the best one to buy 40 batteries, by using algebra we will see that the best offer is offer-B
<h3>
How to find the best offer?</h3>
Here we just need to see which would be the cost of 40 batteries which each offer.
For offer-A, a pack of 4 costs £2.52 and we have 1/3 off.
For 40 batteries the cost will be 10 times the above quantity, we get:
10* £2.52 = £25.20
But there is a 1/3 off, so the cost would be 2/3 of the above quantity:
£25.20*(2/3) = £16.80
For offer-B we know that a pack of 5 costs £2.75, so you need to buy 8 of these. And for each 3 you get one free, so you need to buy 6 (and get 2 free ones). The cost of 6 of these is:
6*£2.75 = $16.50
From this, we can conclude that offer-B is the best one.

Answer:
16 square inches.
Step-by-step explanation:
Split the shape into a rectangle and square. To solve for square, just mulitple the 2 sides (2 x 2) and you get an area of 4. To solve for the rectangle, you can multiple the 6 and 2 to get the area of 12. Add the 4 and 12 together and you get 16 square inches. Hope this helps!

Answer:
x² - 10x + 21
Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.
This can be done as follows:
(x - 3)(x - 7)
x(x) + x(-7) -3(x) -3(-7)
x² - 7x - 3x + 21
x² - 10x + 21
Hope this helps :)
