Answer:
* Lucy spent £289.2 on tiles *
Step-by-step explanation:
We know that the tiles are present in a 13 to 2 ratio ( 13 : 2 ) so if there are 16 blue tiles that she buys, the number of red tiles bought should be represented the following -
= 
... now this is only assuming that the 13 : 2 ratio is meant by white : blue tiles. Let's solve through cross - multiplication,
13 
16 = 2
,
208 = 2,
= 104 white tiles
So if there are 104 white tiles, and 16 blue tiles, we can determine the total amount Lucy spent on tiles by associating the cost to the type of tile,
£2.80 16 = £44.8,
£2.35 104 = £244.4,
Total Amount Lucy Spent on Tiles = £44.8 + £244.4 = £289.2
When x=5 ,
5(x+2) - 4 = 5(5+2) - 4 = 5(7) - 4 = 35 - 4 = <em>31</em>

The dimensions of the tent are 9 by 15 at the base and 7 units of height. So, the voume is defined as
Replacing all given values, we have
Therefore, the right answer is the second choice.
Well the only thing that would make these triangles not congruent is dilation, Thus, translation, reflection, and rotations all make the triangles congruent.
The bottom one and third one are not congruent while everything else is.
