The sum of the given decimal numbers is -7.68
<h3>Sum of decimal numbers</h3>
Decimal numbers are numbers that contains decimal points. Given the expression below;
4.62 + (−12.3).
Convert to fraction to have:
4.62 + (−12.3) = 462/100 - 123/10
Find the LCM
4.62 + (−12.3) = 462-1230/100
4.62 + (−12.3) = -768/100
4.62 + (−12.3) =-7.68
Hence the sum of the given decimal numbers is -7.68

You can make 6 different towers. If red was at the bottom, there'd be two different possibilities for that: red, yellow, blue, and red, blue, yellow. Same for if blue was at the bottom: blue, red, yellow, and blue, yellow, red. Yellow also applies: yellow, red, blue, and yellow, blue, red. 3*2=6, so 6 possible towers.

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.
