Which are the prime factors of the polynomial 24x4 – 3x? Check all that apply.
Luba_88 [7]

The  prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and  (4x2 + 2x + 1)

<h3>Prime factorization</h3>

Given the polynomial function expressed as:

24x^4 – 3x

Factorize

y = 24x^4 – 3x

Factor out the GCF

y = 3x(8x^3 - 1)


Factor the expression in parenthesis

y = 3x((2x)^3 - 1^3)

y = 3x(2x-1)((2x)^2 + 1^2 +2x)

y = 3x(2x -1)(4x^2 +2x + 1)

Hence the  prime factors of the polynomial 24x4 – 3x are 3x, 2x -1 and  (4x2 + 2x + 1)

What is the surface area of the regular pyramid given below?
yuradex [85]

For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:

SA = \frac {1} {2} p * S + A_ {b}

Where:

p: It is the perimeter of the base

S: It's the inclination

A_ {b}: It is the area of the base

Substituting:

A_ {b} = 7 ^ 2 = 49units ^ 2\\p = 7 + 7 + 7 + 7 = 28units\\S = 10units\\SA = \frac {1} {2} 28 * 10 + 49\\SA = 140 + 49\\SA = 189 \ units ^ 2
