2x² - 128
2(x² - 64), but (x² - 64) = x² - 8² (difference of 2 squares),[a²-b²=(a-b)(a+b)]
2(x² - 64) = 2(x² - 8²) = 2(x-8)(x+8)
The probability of randomly selecting a can of pink paint is P = 1/3, so the correct option is A.
<h3>What is the chance that he will paint his bedroom pink?</h3>
Assuming that all the cans of paint have the same probability of being randomly selected, the probability that he will choose a pink can is equal to the quotient between the number of pink cans and the total number of cans.
There are 2 cans of white, 4 cans of green, and 3 cans of pink, so a total of 9 cans.
Then the probability is:
P = 3/9 = 1/3.
The correct option is A.

Answer:
Step-by-step explanation:
So we have:
Multiply both sides by 11:
The right side cancels:
Multiply the left:
Thus, the value of q is 33.
Answer:
A die has 6 numbers.
So 6 numbers them being
1, 2, 3, 4, 5, 6
There’s only one number greater then 5 which is 6.
Since its 6 numbers, a die has a 1/6 chance of getting your desired number.
So it’s a 1/6 chance.
Answer:
Step-by-step explanation:
4*3^x+1=27+(3^2)^x
(3^2)^x=(3^x)^2
3^x=t
4t+1=27+t^2
t^2-4t+27-1=0
t^2-4t+26=0
delta=4^2-4*1*26=16-84=-68<0
the equation has not real solutions
