Zero because you combine 12z and 15z because they are like terms giving you 27z. The equation now looks like 27z-6=27z-5. Subtract 27z on both sides leaving you -6=-5 which is false. So the equation has 0 solutions.

Step-by-step explanation:
The area of the shaded portion inside the given triangle is; 1254 square meters
<h3>How to find the area of shaded portion?</h3>
Looking at the given image, we can say that;
Area of Shaded Portion = Area of Triangle - Area of Circle
Area of Triangle = ¹/₂ * 56 * 56
Area of Triangle = 1568 m²
Area of Circle = πr²
Area of Circle = π * (20/2)²
Area of Circle = 314 m²
Thus;
Area of Shaded Portion = 1568 m² - 314 m²
Area of Shaded Portion = 1254 square meters

I can help you if you show me your h.w.
Okay, so I'm assuming you want to know the intersection?
-5 = -1/2x - 2
-3 = -1/2x
1/2x = 3
x = 6
(6, -5)
