Answer:
(a + b -c) x (x +y )
Step-by-step explanation:
Firstly, factor out x from the expression
Then, factor out the y from the expression
Answer:

Step-by-step explanation:
The question is not correct (particularly the expression for the area)
A=2lh+2wh
Now we are expected to solve for l, that is we are going to make l subject of the formula, we have
let us take the second term on the RHS to the LHS

we can now divide both sides by 2h we have

hence the expression for the length is 
20 because 100 plants would have 60 flowers and 40 vegetables so 50% which is half would be 30 flowers and 20 vegetables
5 x 0.4 = 2 and

= 1.4142....... which is an irrational number
