Hey there!

  • Say that you have 3 books in 3 rows on shelves  in the library
  • Row1:3
  • Row2:3
  • Row3:3
  1. 3,6,9
  • 3+3+3
  • 3+3= 6
  • 6+3 = 9
  • 3*3\neq 8
  • 3*3= 9  So, the correct answer should be: \boxed{9}

Good luck on your assignment and enjoy your day!

3x3 is the same thing of saying adding 3 to itself, 3 times. This looks like this⇩

3 + 3 + 3

Then simplify by first doing 3 + 3 first, then adding the final 3 after⇩

6 + 3

Four subtracted from twice a number is two. what is the number
EastWind [94]

Answer: 3

Step-by-step explanation:

      First, we will write a mathematical equation for the phrase given.

-> Let n be "a number"

             four subtracted from twice a number is two

             four subtracted from twice a number = 2

             (twice a number) - 4 = 2

             2n - 4 = 2

      Now, we will solve this equation by isolating the variable.

             2n - 4 = 2

             2n = 6

             n = 3

Inverse square root (x+3)​
QveST [7]

Answer:

The inverse function is f(x) = x^2 - 3

Step-by-step explanation:

To find the inverse of any function, start by switching the x and f(x) values.

f(x) = √(x + 3)

x = √(f(x) + 3)

Now solve for the new f(x). The result will be your inverse function.

x = √(f(x) + 3)

x^2 = f(x) + 3

x^2 - 3 = f(x)
