Factored
(x^2 +6)(x^2 - 6)
(x^2 + 6)(x + sqrt (6))(x - sqrt (6))
2√31
I DONT KNOW!
THERES NO EXPLAINATION IN MATH.. LETS BE HONEST HERE.
You write the problem as a mathematical expression
3x^2 + 30x + 75 =
Factor: 3 out of 3x^2 + 30x + 75.
3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
by using Pythagoras theorem c2= a2 + b2
so let's say c= 17 and a= 7, let's calculate for b
(17)^2 = (7)^2 + b2
289= 49+b2
289 - 49 = b2
240 =b2
√249 = b
b = 15 . 49
The probability of you picking a large or blue is 45/83. You add the probability of picking a large (25/83) and the probability of picking a blue (20/83). That’s where you get the total from.
