Find the length of side ab give answer to 1dp

B is 62 degrees

And hypotenuse is 12cm

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

thus, the first answer choice, y = sec x, is the correct one

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
