The sum of all angles in a triangle is 180.
AngleA+AngleB+AngleC=180
20+40+AngleC=180
AngleC=120
4 units is the width.
10 units is the length. If we put this in, we get (l*w) 10*4 for the area, which is 40 square units. This is a true statement. Also, 4*2 is 8, and 2 more units than 8 is 10 units.
Answer:
B)y = 3x^2 - 3x-18
Step-by-step explanation:
y = (3x – 9)(x + 2)
y = 3x*x+3x*2-9*x-9*2
y = 3x^2 +6x-9x-18
y = 3x^2 - 3x-18
