Suppose the dimensions of some rectangles and squares were measured in feet.
which statements are true?

The second one, third and fourth one

Step-by-step explanation:

To find area you multiply the length and the width together and when you have something with multiplied exponents you add the exponents so if you had x∧3 ·x∧4 the answer would be x∧7  The first statement is not true because the length and width are in terms of a and the area is in terms of x.

I hope this helps and please don't hesitate to ask if there is anything still unclear!

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
