Answer:
Paula would choose the side with all of the mushrooms and half of the pepperoni. She wont choose any sausage because she doesn't like it, but luckily David likes sausage twice as much as mushroom so he's fine with getting all of the sausage and half of the pepperoni. They both equally like pepperoni so it makes sense for them to share.
Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.

Answer:
5
Step-by-step explanation:
The difference identity of two squares can be stated as:
a² - b² = (a + b)(a -b)
i.e. the product of sum of two numbers with the difference of two numbers. This can be easily proved.
For example, Let a = 4 and b = 3
so, a² - b² = 16 - 9 = 7
a + b = 4 + 3 = 7
a - b =4 - 3 = 1
(a + b )(a - b) = 7 x 1 = 7
Thus,
a² - b² = (a+b)(a-b)
So, option C gives the correct answer
