Answer:
Step-by-step explanation:
I think you mean a^2 + 16a + 64.
The x-intercepts are the values of a for which the polynomial equals zero.
a^2 + 16a + 64 = (a+8)^2 = 0
a = 8
The x-intercept is 8.
Answer:
The answer is C because they are both equal and they are in the same spot
Step-by-step explanation:
( This is for question number 1)
For number two it’s B) SAS
The probability of rolling a 6 on the 1st roll is
![\frac{1}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B6%7D%20)
, since there is only 1 out of 6 sides of the dice that has six pips.
The probability of rolling an odd number is
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
, since there are 3 out of 6 sides of the dice that has an odd number of pips.
![\frac{3}{6} = \frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B6%7D%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D)
Then the probablity of both events happening one after another is
![\frac{1}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B12%7D%20)
. You have to multiply both probabilities of the events:
Answer:
It can't be simplified anymore
Step-by-step explanation:
2 times 17 = 24
3 times 19 = 57
