Step-by-step explanation:
X - 4 = 0
X = 4
X - 2 = 0
X = 2
So the values of x are 2 and 4
Suppose the smallest angle is x
the largest is 5x-3
the remaining angle is 2x-1
the three angles make a sum of 180: x+5x-3+2x-1=180
8x-4=180
8x=184
x=23
the smallest angle is 23 degree.
Answer:
(1,7.5)
Step-by-step explanation:
(x₁ + x₂ / 2 , y₁ + y₂ / 2)
(-2 + 4 / 2 , 6 + 9 / 2)
(2 / 2 , 15 / 2)
(1,7.5)
You can simply expand the factorised form out:
y = 14x² - 21x + 10x - 15
y = 14x² -11x -15
