The statements that are rue for <span>all invertible n×n matrices A and B are:
</span><span>(A+B)(A−B)=A^2−B^2
</span>and
<span>(ABA^−1)^4=AB^4A^−1
</span>From the above results we can conclude that the correct options among all the options that are given in the question are option "B" and option "E". I hope the answer helps you.
Answer:
Answer is first line
Step-by-step explanation:
-7(x+9) >= 37+3x
Going to solve for x:
-7x - 63 >= 37 + 3x
-7x - 3x >= 37 + 63
-10x >= 100
x <= 100/-10 (notice the change in equality because we divided by negative)
x <= -10
That would be 1

65.25 - 40.50 = How much longer the pool is than wide
= 24.75 longer
It is also or about 38%.
40=6.95c+5.25
The $40 is what you want it all to equal, so that goes to one side by itself.
The CDs are 6.95 each, so they get a variable to show that.
The 5.95 is added to that, showing that it's only charged once.
Then, all you have to do is solve for c, which is the number of CD's you can buy.
