Mathematics

Answer:

3x + 2

Step-by-step explanation:

This is the answer because if you distribute 3 to x-1, it would be 3x - 3, and if you add 5, you would get 3x + 2

First you must distribute the 3 to the numbers inside the parentheses, which would be x and -1...

5 + (3*x) + (3 * (-1) )

5 + 3x + (-3)

5 + 3x - 3

Now you must combine like terms. Like terms are numbers that have matching variables OR are numbers with out variables. In this case the like terms are 5 and -3, since they both don't have any variables attached.

(5 + (-3) ) + 3x

2 + 3x

3x + 2 is  5 + 3(x - 1) simplified completely

Hope this helped!

Given the algebraic expression 12x+12/x²-1 do the following:
andre [41]

The value of the function is x is 7 and 4 are 2 and 12 respectively

<h3>Function and values</h3>

Given the function of the variable x below;

f(x) = 12x+12/x²-1

If the value of x is 7, hence;

f(7) = 12(7)+12/(7)²-1

f(7) = 84+12/48
f(7) = 96/48

f(7) = 2

If the value of x is 4, hence;

f(4) = 12(4)+12/(4)²-1

f(4) = 48+12/15

f(4) = 60/5

f(4) = 12

Hence the value of the function is x is 7 and 4 are 2 and 12 respectively

Which statement about the equation 3x ^ 2 + 9x - 12 = 0 is true ? 1 . The product of the roots is -12 . 2 The product of the roo
svetlana [45]

Answer:

Option : The product of the roots is - 4

Step-by-step explanation:

3x^2 + 9x - 12 = 0\\\\3x^2 + 12x - 3x - 12 = 0\\\\3x(x+4) -3(x+4) = 0\\\\(3x - 3) (x+ 4) = 0\\\\

Therefore the roots are -4 and 1

The product of the roots are -4 x 1 = -4
