Answer:

yes ,Polynomials can be as simple as the expression 4x, or as complicated as the expression . Polynomials are usually written in standard form, which means that the terms are listed in order from the largest exponential value to the term with the smallest exponent.. For example if n = 1, a1 = 7 and a0 = 0 then you get the expression 7x, so 7x is a polynomial

hope this helps:')

Answer:

3 unidades de comprimento

O perímetro de um retângulo de comprimento x e largura x² é dado por:

R=2x+2x^2

Para que ambos os perímetros sejam iguais:

R=Q\\8x=2x+2x^2\\x^2=\frac{6}{2}x\\ x=3

O valor de x é igual a 3 unidades de comprimento.
