Answer:
Step-by-step explanation:
The answer is 4.
Once you add 4, you get:
x^2 -2x + 4 = 7.
The left side is factorable:
(x-2)^2 = 7.
There is your perfect square.

Answer:
Step-by-step explanation:
There are 24 marbles in the bag.
So,
There are 17 marbles that are either white and green.
Therefore,
"the probability of drawing a white marble" is 9/24
=0.375 or approximately as 37.5%.
Probability of drawing first white marble from the bag.
Now,
"The probability of drawing a green marble" is 8/24
=0.333 or approximately as 33.3%.
Probability of drawing a green marble.
Find this using the pythagoream theorem for right triangles.
a^2+b^2=c^2
12^2+9^2=c^2
144+81= c^2
225=c^2
15=c
Final answer: c=15
