Answer:
28
Step-by-step explanation:
So in order to get this answer you want to use the combination formula which is 
Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation
so your going to have something looking like this 
now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.
hope this somewhat helps.
So basically all you have to do is find the area of one of the smaller semi circles by using the formula for the area of a circle (A=πr^2). You know that the length of the larger semi circle's radius is equivalent to 6 cm because the radius of the smaller ones are 3 cm, meaning the diameter would have to be 6 cm and in this case, the length of the smaller semi circles' diameters is equal to the radius of the big semi circle. Then you would find the area of the big semi circle again by using the area of a circle formula, but after getting the answer you would half it, obviously because it's a semi circle. Subtract the are of the smaller semi circle you found earlier from the answer you just got and that's it ;) (you wouldn't have to half the area since there are two smaller semi circles and 1/2 + 1/2 = 1 but u knew that)
Put simply, the answer would be about 88.2644 cm because circles.

Answer:
y is 1 and x is 4
Step-by-step explanation:
becasue the y intercepts at 1 and the x intercepts at 4
24 because she already completed four and if she completes twelve more that that will be 24 hope that helps
