The polynomial 6x5 + 18x7 + 11 represents the height of an elevator over time. Select all the statements that are true The elevator goes up and never comes back down.

The degree of the polynomial is 7.

The polynomial is in standard form.

The start and end of the trip are similar to f(x) = -x.

The elevator is going down for all real numbers.

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
