Answer:

15.58 cm²

Step-by-step explanation:

Let's calculate the whole shape's area and subtract.

5.5 + 3 = 8.5

8.5 × 3.4 = 28.9 cm²

2 × 6 = 12 cm²

2 + 1 = 3

3.4 - 3 = 0.4

0.4 × 3.3 = 1.32 cm²

28.9 cm² - 12 cm² - 1.32 cm² = 15.58 cm²

Help! It says that I need to determine If both equations represent lines which are parallel, perpendicular, or none...
12345 [234]
    4x + 2y = 8     (1)
    8x + 4y = -4y  (2)

A) Two lines are parallel if they have the same gradient
       - putting both equations into the gradient- intercept form ( y = mx + c                where m is the gradient)
            (1) 4x + 2y = 8
                          2y = 8 - 4x
                            y = -2x + 4
             
            (2) 8x + 4y = -4y
      <span>                    </span>8x = -4y - 4y
                            y = \frac{-8x}{-8}
                            y = -x
   <span>Thus the gradient of the two equations are different and as such          the two lines are not parallel
</span>
B)  When two lines are perpendicular, the product of their gradient is -1
                   m_{1} * m_{2} = p
                                             p = (-2) * (-1)
                                             p =  2
<span>          ∴ the two lines are not perpendicular either.</span>

Thus these lines are SKEWED LINES

How would you convert a mass in centigrams to a mass in milligrams??
const2013 [10]
First let's start with the relationship between grams and centigrams and grams and milligrams.

1 gram = 100 centigrams
1 gram = 1000 milligrams

Because these two equations are equal, we can rewrite our equation as 100 centigrams = 1000 milligrams.

Now we divide by 100 to simplify our equation to 1 centigram = 10 milligrams.

With this simplified equation we see that we multiply the number of centigrams by 10 to find the equal number of milligrams.
