Okay so first you need to find the height of the triangle (pythagorean theorm) a^2+b^2=c^2 so here we're looking for b
2^2 + b^2= 4^2 
4+ b^2= 16
-4           -4
b^2=12 square root both b=appx 3.4 
now we have the height and the base
area formula for a triangle is 1/2bh
4*3.4= 13.6 since there are 3 shaded triangles multiply by 3 
13.6*3= 40.8 so the total area shaded is 40.8 hape this helped have a great day!!!

To help solve this, we need to use the slope formula.

(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.

For JL, we will pick points (-5, -3) and (-2, -4).

y1 = -4

y2 = -3

x1 = -2

x2 = -5.

Let's plug these into our formula.

(-3) - (-4) / (-5) - (-2) = -1/3

For LN, we will pick points (-2, -4) and (7, -7).

y1 = -7

y2 = -4

x1 = 7

x2 = -2.

Lets plug these values into our equation.

(-4) - (-7) / (-2) - (7) = -1/3

Therefore,

(-3) - (-4) / (-5) - (-2) = (-4) - (-7) / (-2) - (7)

The correct answer is G.

Mazyrski [523]

Answer:

A)  

3x + 24 + 10 = 5x - 10 - x + 2

34 = 2x -8 - x

34 = x - 8

42 = x

or

<u><em>x = 42 million</em></u>


B)

<u><em>CORRECT! (1.2 million)</em></u>


C)

<u><em>0.028 = 3% if rounded.</em></u>

<u><em>The death rate is 3% </em></u>
