Answer:
<u>The expression is 6v² + 6v - 120</u>
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)
<u>The expression is 6v² + 6v - 120</u>
80/180, because there in all 180 but 80 boys…i think.
