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
C and D is true and others are false
Answer:
x = 4; x = -4
Step-by-step explanation:
|3x| = 12
3x = 12
3x/3 = 12/3
x = 4
3x = -12
3x/3 = -12/3
x = -4
