Answer:
Step-by-step explanation:
A.) x² + 1 = 2x − 3 Make the equation into ax² + bx + c = 0. Subtract 2x on both sides, and add 3 on both sides to set the equation equal to 0
x² + 1 - 2x + 3 = 2x - 2x - 3 + 3
x² - 2x + 4 = 0
a = 1
b = -2
c = 4 This is not the answer because b = 2 not -2, and c = -4 not 4
B.) x² - 2x − 1 = 3 Subtract 3 on both sides to set the equation = 0
x² - 2x - 4 = 0
a = 1
b = -2
c = -4 This is not the answer because b = 2 not -2
C. x² + 2x - 1 = 3 Subtract 3 on both sides to set the equation = 0
x² + 2x - 4 = 0
a = 1
b = 2
c = -4 This is your answer
D. x² + 2x - 1 = -3 Add 3 on both sides to set the equation = 0
x² + 2x + 2 = 0
a = 1
b = 2
c = 2 This is not the answer because c = -4 not 2
Hope this helps :)

Answer:
32.5 ft
Step-by-step explanation:
The length of the side opposite the given angle is found using the sine relation:
Sin = Opposite/Hypotenuse
height on building = (33 ft)·sin(80°) ≈ 32.5 ft
The ladder reaches about 32.5 feet up the side of the building.
_____
<em>Additional comment</em>
The maximum angle compliant with OSHA safety rules is 75.5°.
Given:
7 kg turkey
cooking instructions:
over 4kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving.
7kg * 20 minutes/kg = 140 minutes
140 minutes + 90 minutes = 230 minutes
230 minutes + 30 minutes rest = 260 minutes
260 minutes * 1hr/60 minutes = 4 hours 20 minutes
17:15 is 5:15 pm
17:15 - 4:20 = 12:55 pm
Adam should start cooking at 12:55 pm
