Part 1 out of 2

Write an expression for 6 times the square of a car's speed plus 6 times the car's speed

minus 120. Use v for the car's speed. Do not factor the expression.

The expression is

Next

The expression is 6v² + 6v - 120

Step-by-step explanation:

v = Car's speed

Let's write the expression for 6 times the square of a car's speed plus 6 times the car's speed minus 120, this way:

6v² = 6 times the square of a car's speed

6v - 120 = 6 times the car's speed minus 120

Now, let's add the operator (+):

6v² (6 times the square of a car's speed) + 6v - 120 (6 times the car's speed minus 120)

The expression is 6v² + 6v - 120
