Show that if A is invertible, then . What theorem(s) should be used to examine the quantity ? Select all that apply. A. If one row of a square matrix A is multiplied by k to produce B, then k. B. A square matrix A is invertible if and only if 0. C. If A is an nn matrix, then . D. If A and B are nn matrices, then det AB.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

there is nothing below so i cannot

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
