Study the expression: y + 3.25 + 4z + 7. how many terms are there? list the variables. list the constant

2 variables , and 3.25, 4, and 7 are the constants.

Step-by-step explanation:

⇒ y + 3.25 + 4z + 7

step-by-step explanation:

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
