Answer and Step-by-step explanation:

When it says (f + g)(x), it means that it wants you to add the functions together.

So, let's add them.

(2x^2 + 6x - 4) + (5x^3 -6x^2-3)\\\\\\5x^3 - 4x^2 + 6x - 7\\\\\\\\\\\\\\5x^3 - 4x^2 + 6x - 7is the answer. (Answer choice B.)

Which special case is represented by x? - 121?
marissa [1.9K]

Answer:

A. the difference of two squares

Step-by-step explanation:

Please use the symbol " ^ " to indicate exponentiation.

Then we have x^2 - 11^2, which is the difference of two squares:

x^2 is a square, the square of x; and 11^2 is a square, the square of 11.

A. the difference of two squares

Note that a "difference of squares" is easily factored:

a² - b² = (a - b)(a + b)

and so your x² - 11² factors as follows:  (x - 11)(x + 11)

How do i find the value of x on this problem?
zaharov [31]

Answer:

x = 7

Step-by-step explanation:

The proportion is

14/6 = 21/(3x - 12)                 Cross Multiply

14*(3x - 12) = 6*21                 Remove the brackets and combine

42x - 168 = 126                     Add 168 to both sides

42x = 126 + 168

42x =  294                           Divide by 42

x = 294/42

x = 7
