Which polynomial is written in standard form?

Choice B)

-5x^3 + 9x^2 + 2x

Explanation:

Standard form is where the largest exponent term goes first, then the next largest, and so on. The exponents are decreasing when moving from left to right.

So that's why -5x^3+9x^2+2x is in standard form. Think of the 2x at the end as 2x^1. That might help show the exponents are decreasing (3,2,1).

The largest exponent is the degree, meaning that we have a third degree polynomial (aka cubic polynomial).

The first term -5x^3 is considered the leading term and -5 is the leading coefficient.

step-by-step explanation:

no of data

divide by no of mode

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
