Evaluate the expression 2n, if n = 4. first answer gets brainlist i'm on my exam now so im serious.

The answer is 8. 2n means 2*n, which is 2*4.

Step-by-step explanation

8

Step-by-step explanation:

2 × 4 = 8

 Slope = -1

 x-intercept = 3/-1 = -3.00000

 f-intercept = 3/-1 = -3.00000

Slope = 0.667/2.000 = 0.333

 x-intercept = 3/-1 = -3.00000

 f-intercept = 3/3 = 1

Slope = 0.400/2.000 = 0.200

 x-intercept = 3/-1 = -3.00000

f-intercept = 3/5 = 0.60000

Slope = 0.286/2.000 = 0.143

 x-intercept = 3/-1 = -3.00000

 f-intercept = 3/7 = 0.42857
