Which expression is equivalent to 6x+8?
A 2(3x-4)
B 2(3x+4)
C 2(4x+6)
D 2(3x+8)

B

Step-by-step explanation:

=> 6x+8

We see that 6 and 8 have following factors:

=> 2.3x+2.4

Taking 2 as common, we get

=> 2(3x+4)

This is equivalent to option B

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
