What are two solutions of 3 + 4 |x/2 + 3| = 11?
Alex
3 + 4abs(x/2 + 3) = 11 Subtract 3
4 abs(x/2 + 3) = 11 - 3
4 abs(x/2 + 3) = 8 Divide by 4
abs(x/2 + 3) = 8/4
abs(x/2 + 3) = 2

Solution 1
x/2 + 3 = 2 Subtract 3
x/2 = 2 - 3
x/2 = - 1 Multiply by 2
x/2 *2 = - 2
x = - 2

Solution 2
x/2 + 3 = - 2
x/2 = - 2 - 3
x/2 = - 5 Multiply by 2
x = -5 * 2
x = -10

Solutions
x = - 2 <<<< answer 1
x = -10 <<<< answer 2

Find the area.of the shape below
Marta_Voda [28]

Answer: 464 km²

Step-by-step explanation:

      We will break this shape up into two parts. You can do this in two different ways, see attached for how I did it.

      Area of a rectangle is A = L * W;

40 km * 9 km = 360 km²

13km * 8 km = 104 km²

     Now we will add them together for total area:

360 km² + 104 km² = 464 km²
