ANSWER :
The values of x are -8 and 8
EXPLANATION :
From the problem, we have the equation :
![x^2-47=17](https://tex.z-dn.net/?f=x%5E2-47%3D17)
Add 47 to both sides :
![\begin{gathered} x^2-47+47=17+47 \\ x^2=64 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%5E2-47%2B47%3D17%2B47%20%5C%5C%20x%5E2%3D64%20%5Cend%7Bgathered%7D)
Take the square root of both sides :
Answer:

Step-by-step explanation:
I looked it up HOPE THIS HELPS
No clue, sorry ... about that
She has 7 soccer trophies.
So lets assume she wants to display it in a straight line:
The 1st has 7 ways
The 2nd has 6 ways
The 3rd has 5 ways
The 4th has 4 ways
until the last.
Total = 7 × 6 ×5 × 4 × 3 × 2 × 1 = 5040 ways.
Answer:
P(blue then red)=5/169
Step-by-step explanation:
the probability of picking the blue is 4/26 it's replaced so the total jellybeans doesn't change therefore the sample space doesn't change. the probability of picking a red is 5/26
to find the probability of picking them in that order, you multiply the two together
(4/26)x(5/26)=20/676
reducing that we get:
P(blue then red)=5/169
