Answer:
The area of the shape is 89m²
Step-by-step explanation:
You need to subtract the area of the empty triangle from the area of the rectangle.
The rectangle's area is 13m × 8m = 104m²
The triangle's area is (6m × (13 - 8)m) / 2 = (6 × 5) / 2 m² = 15m²
Subtract the triangle's area from the rectangle:
104m² - 15m²
= 89m²
It’s going to be -18
First add 6 to both sides to get x by itself
-6x + 18 = -6
+6 +6
X + 18 = 0
Then minus the 18 giving you x = -18
