Answer:
Step-by-step explanation:
5 red
15 black
10 white
altogether the is 30 marbles so that means it is 'out of' 30
and because the is 5 red it would be 5/30
and because the is 10 white it would be 10/30
that should be the answer but if you have to work the total all together then it would be 15/30
hope this helps :)
To complete the square you halve the coefficient of the x term and square it. Half of 14 is 7 and 7² is 49. So we add 49 and subtract 49, which means we are not changing the value of the quadratic. So we have x²+14x+49-49+2. This can be written: (x²+14x+49)-49+2, which is (x+7)²-47, which is answer a.
