Find the surface area of a square prism with a side measure of 15
Phoenix [80]
Since the length is 15, and the width would be 15, you need to first do 15 x 15.

15 x 15 = 225


Multiply the 6 faces.

225x6

Your final answer would be 1,350.

I have no idea what im doing
omeli [17]

Answer:

  • x = - 6

Step-by-step explanation:

A hole is an input value that makes both numerator and denominator equal to zero.

<u>Let's factorize the numerator and denominator:</u>

  • 3x² - 108 = 3(x² - 36) = 3(x + 6)(x - 6)
  • x² + 2x - 24 = x² + 6x - 4x - 24 = x(x + 6) - 4(x + 6) = (x - 4)(x + 6)

<u>We have same factor of x + 6:</u>

  • x + 6 = 0
  • x = - 6 is a hole
