Hello!
x² - 4x + 6 = 9 <=>
<=> x² - 4x + 6 - 9 = 0 <=>
<=> x² - 4x - 3 = 0 <=>
<=> x = -(-4)±√(-4)²-4×1×(-3)/2×1 <=>
<=> x = 4±√16+12/2 <=>
<=> x = 4±√28/2 <=>
<=> x = 4±2√7/2 =>
=> x = 4+2√7/2 and x = 4-2√7/2 =>
=> x = 2+√7 and x = 2-√7
The equation has two solutions.
Good luck! :)
Answer:
1170 m²
Step-by-step explanation:
Parallelogram: 40 x 18 = 720
triangle: (50 x 18) / 2 = 450
total area: 720 + 450 = 1170
g(x) = 4x + 2
Step-by-step explanation:
f(x) = x + 2
f(4x) = 4x + 2
