Answer:
; indirect variation ; x = 2.4
<u>Step-by-step explanation:</u>
direct variation is when:
; where k is the constant rate
indirect variation is when: xy = k ; where k is the constant rate
In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation: 
since k = 24, then input y = 10 and k = 24 into the equation above:



x = 2.4
Answer:

Step-by-step explanation:

Take
& factorise it at first.

Now factorise the next set :
.

Now, multiply the two simplified results.


The two expressions are equivalent because they have the same value regardless of the number of substituted in for y
11.5 * 2.3 = large door size
large door size / 12 = large door size in feet
large door size in feet / 10 = how many large doors can be cut from the board. (you have to round it down if there's a decimal- no 1/2 doors.)
