Answer:
x²-4x+7
-x²-6x-12
Step-by-step explanation:
1.) the first thing we do is expand the exponent (or mulitply (x-2)(x-2) the images below will show you how to do that
We get x²-4x+4 and then just need to add three
x²-4x+7
2.)
We do the same thing (expand the exponent) and get x²+6x+9
which means so far we have
-(x²+6x+9)-3
carry out the negative sign and subtract 3
-x²-6x-12

Answer:
5(9+x)
Step-by-step explanation:
5 x 9 = 45
then if do 5 times x it would look like 5x
He got 16 questions right (5x16=80) and 10 wrong (8x10=80) He got paid $80 but also had to pay $80.
Answer:
The question is incomplete, the complete question will be:
Suppose you are offered the opportunity to roll a six-sided die, whose faces are 1, 2, 3, 4, 5, and 6. You have no reason to believe one face is any more likely that another. After the roll, you will be paid $1 times and you have the option to throw a die up to three times. You will earn the face value of the die. You have the option to stop after each throw and walk away with the money earned. The earnings are not additive. What is the expected payoff of this game?
