Flag Let A, B, and C be non-singular 2x2 matrices, I the 2x2 identity matrix and k a scalar. The following statements are incorrect. For each statement, write down the correct version of the right hand side.

(a) (A+B)2 = A2+2AB+B2

(b) (A-kI)3 = A3-3kA2+3k2A-k3

(c) CA=B C=B/A

Please show logical and detailed work.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

ab will be equal to
