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.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
