Which polynomials are in standard form?

A. x^2 + 3x + 2

D. 3x^4 + 4x^3 - 3x^2 - 1

E. 3t^3 + 3t^2 + 2t

Step-by-step explanation:

Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.

option A, D  and E

Step-by-step explanation:

The polynomial is in standard form only when the exponents starts with largest exponent and keeps on decreasing from greatest to least

has largest exponent 2 and then x

option B and C has exponents that are not in order.

has largest exponent 4 and the exponents are from greatest to least.

has largest exponent 4 and the exponents are from greatest to least.

last option has exponents that are not in order.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
