Answer:
4 tiles are added to each figure in the tile pattern.
Simply simplify:
7a³(7a²)-4a^6 ⇒ 49a^6 - 4a^6 ⇒ 45a^6
Hope that helps!
I set this up as an inequality,

. If you take the cubed root of 800, you get the lower bound of the side length, which is 9.2. Then I just worked my way up until I hit the first number that put me over a volume of 800. That number is 9.29, because 9.28 cubed is 799.1 (not high enough) and 9.29 cubed is 801.8. Therefore, the bounds of the sides exist within a conjunction:

. That's the best I could come up with to help on that one. Wasn't sure if there was another method you were taught at school. I just used common sense more than any rule.
4+15+11+5+7+10= 50 cm
10cm was the missing one
Using proportions, it is found that the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The proportion of <u>pizza places per person</u> in each block of the town is given as follows:
- North: 32/(221 x 15) = 0.0096 < 1.
- South: 28/(22 x 150) = 0.0084 < 1.
Both proportions are less than 0.01, hence the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.
