Surface area = 2(6*3) + 2(6*2) + 2*(2*3) = 36+24+12 = 72 cm^2
361 congruent square tiles would be needed to cover the square shaped floor.
<h3>Equation</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.
Counting one tile twice, there are:
- 37=2x-1
- x=19 tiles on each side.
19² = 361
361 congruent square tiles would be needed to cover the square shaped floor.

You need to use the cross product method to find your answer :
1 pizza = 2 ½ cups
3 pizzas = × cups
((2 ½) • 3) ÷ 1 = × cups
7 ½ ÷ 1 = × cups
7 ½ = × cups
⇨ So your answer is: You would need to use 7 ½ cups of flour to make 3 handmade pizzas!
There you go. I really hope this helped, if there’s anything just let me know! ☻

Step-by-step explanation:
1) Collect like terms.

2) Simplify.

So, therefor, the answer is -17y - 16z + 4.
