Answer:

Third side = 4

Step-by-step explanation:

Use Pythagoras theorem :

C = longer side, a = 10, b ?

c^2 = a^2 + b^2

(2 \sqrt{29})^2 = 10^2 + b^2\\\\4 \times 29 = 100 + b^2\\\\116 - 100 = b^2\\\\b^2 = 16 \\\\b = 4

Which expression is a prime polynomial?
irakobra [83]

The expression that is a prime polynomial is:

B. x^3 - 27y^2.

<h3>What is a prime polynomial?</h3>

A prime polynomial is a polynomial that cannot be factored.

In this problem, item b gives a prime polynomial, as:

  • In item a, 3 is a common factor, hence the polynomial can be factored.
  • In item c, x is a common factor, hence the polynomial can be factored.
  • In item d, the polynomial can be factored according to it's roots.

F(x)=-12x - 2x + 60x² +14x-60
Leona [35]

Answer:

x=±1. are the factors of the quadratic equation.

Step-by-step explanation:

Given quadratic expression, f(x)=-12x - 2x + 60x² +14x-60

Rearranging and adding the terms in the expression and equating to zero.

f(x)= 60x² -60=0

60(x² - 1) =0

The zero product property states that if the product of a⋅b=0 then either a or b equal zero or both of them must be equal to zero. This basic property helps us solve the quadratic equations like (x+2)(x-5)=0 where x =-2,5.

from the zero product property we can infer that 60≠0⇒x² - 1=0

⇒(x+1)×(x-1) = 0

⇒x=±1.

Therefore, x=±1. are the factors of the quadratic equation.
