Answer: percentage of profit on the skirt is 11.1%
Step by step:
Let G denote price of gloves, and S the price of skirt, and let g dente the original cost of the gloves and s the cost of skirt. I will be using $ for the currency unit instead of the pound.
The sale equation is
$48 = G + S
100% profit on the gloves means:
G = 2 * g = 2 * $4
On the skirt, the profit is unknown ("x"):
S = x + s
We know that the total profit (total sale - total cost) after the sale is is 20%:
$48 - (s + $4) = 0.2 * (s + $4)
which finally gives us two equations with two unknowns:
$48 - (s + $4) = 0.2 * (s + $4)
$48 = 2 * $4 + x + s
which is straight-forward to solve. I got solutions as follows:
s = $36, x = $4
so the percentage of profit on the skirt is 100% * 4/36 = 11.1%
Answer:

Step-by-step explanation:
It is helpful to know the special forms for factoring of the difference of squares and for the square of a binomial. In any event, you can always multiply out the factors and compare the result to the list of polynomials on the left.
a² - b² = (a -b)(a +b)
(a -b)² = a² -2ab +b²
The last one requires you to collect terms before factoring.
4y² +5y -6
_____
From a "test-taking" point of view, you can see that the final constant of each of the polynomials on the left is different. This means you can make the correct choices by matching the product of constants on the right.
For example, the first one will have a constant of (-6)² = 36, matching the final constant of polynomial number 4.
