I feel like being nice, first two answers will get 50 points, the first one to answer gets the brainliest.. (You can put any answer you want it doesn't have to be correct.) If you go to my profile and press thank you, i might do more of these.

1×1 = ?

you are so so nice, to give away such big points...may God bless you and stay home and be safe :)

Step-by-step explanation:

1 x 1 is obviously 1

any number multiplied by one that answers that number is the same number.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
