Answer:
8,000,000,000 text messages every month.
Step-by-step explanation:
means there will be 9 zeroes at the end of 1. So it will be 1,000,000,000.
So 8* 1,000,000,000 will be 8,000,000,000 text messages every month.
(x - 2)(x² + 2x + 4)
A difference of cubes factors in general as
• a³ - b³ = (a - b)(a² + ab + b² )
note 8 = 2³ = 8 ⇒ b = 2 , with a = x
Hence
x³ - 8
= x³ - 2³
= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
I think it's -6x-18, this queston uses distributive property, so you must multiply each term inside the parenthesis to the number outside the parenthesis.
Let x represent the number:
2/3(x)+15=9
2/3(x)= -6
x= -6/(2/3)
x= -6*(3/2)
x= -9
y = 13,250
I discover that from this equation multiplying $10,000 by 1.325 gives me 13,250.
