Step-by-step explanation:
To complete the square, take half of the second coefficient, square it, then add the result to both sides.
(-8/2)² = (-4)² = 16
x² − 8x + 16 = 9 + 16
Solving:
(x − 4)² = 25
x − 4 = ±5
x = 4 ± 5
x = -1 or 9
X is approximately equal to 5.7 miles
D is the answer.. hope u didn’t stress yourself out with that question
The sum of the interior angles for a triangle ALWAYS equal 180 degrees. So if M1 = 30 and M2 = 45, then M3 = 105. Hope this answers your question!
