<h2>
7 - 3 + (7 x 3) =
24 </h2>
Step-by-step explanation:
Here, the given expression is:
7 3 7 3 = 24
Here, to get the desired expression:
7 - 3 = 4
4 + ( 7 x 3 ) = 4 + (21) = 24 = Right Side.
So, the given expression can be written as:
7 - 3 + (7 x 3) = 24

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
Answer:
The answer is the option E
120\°
Step-by-step explanation:
In the problem that the student factored incorrectly, they left out a term. Even though you factored out 2xy, you still need to leave a 1 in its place, so you can distribute it back out. If you distribute out the incorrectly factored equation, you will get 6x^9y^2. If you distribute out 2xy(3x^8y+1), you will get 6x^9y^2+2xy.
