Answer:

D

Step-by-step explanation:

x/(x²+3x+2) - 1/[(x+2)(x+1)]

x² + 3x + 2 = x² + 2x + x + 2

= x(x + 2) + (x + 2)

= (x + 2)(x + 1)

= x/[(x+2)(x+1)] - 1/[(x+2)(x+1)]

= (x-1)/[(x+2)(x+1)]

= (x-1)/(x²+3x+2)

5 x 40 = 200

200 x 3 = 600

**Answer:**

1

**Step-by-step explanation:**

identify two points on the graph:

1. (0, 4)

2. (-2, 2)

use slope formula: (y² - y¹) / (x² - x¹)

1. (2 - 4) / (-2 - 0) = -2 / -2 = 1

slope = 1

The number half of 25 is 12.5.

**Answer:**

X = -12

**Step-by-step explanation:**

-10X + 1 +7X = 37

-10X + 7X + 1 = 37 {Add the like terms}

-3X + 1 = 37 {Subtract 1 form both sides}

-3X + 1 -1 = 37 -1

-3X = 36 {Divide both sides by (-3)}

X = -12
