Which expression is equivalent to 2x2 - 2x + 7? - (4x+12) + (2x2–6x+5)• (x2–5x+13)+(x2 +3x-6). (4x? -6x+ 11 ) + (2x² - 4x+4)(5x® – 8x+120) + (-3x2 + 10x= 13)

B)

Step-by-step explanation:

Let's simplify the given options and find the correct answer.

The given expression is

Let's take the option A and simplify.

Distributing the negative sign and simplify.

Simplify the like terms.

Which is not equal to the given expression.

Let's take the option B and simplify.

Simplify the like terms, we get

Which is equal to the given expression

Therefore, the answer is B)

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
