Part a : you could draw a line from each corner to the middle
This would give you 7 triangles in total
Part b : area of one triangle : 4.5*7.8 = 35.1 / 2 = 17.55in <-- area of 1 triangle
Part c : so if there are 7 triangles and the area of 1 triangle is 17.55, you would do:
7 * 17.55 = 122.85
Answer:
y = -16.9
Step-by-step explanation:
<u>→Add 0.8y to both sides:</u>
-0.8y + 5.49 = -19.86 - 2.3y
5.49 = -19.86 - 1.5y
<u>→Add 19.86 to both sides:</u>
25.35 = -1.5y
<u>→Divide both sides by -1.5:</u>
-16.9 = y
