Answer:
x=−2+3√2
Step-by-step explanation:
x2+4x+4−18=18−18
x2+4x−14=0
For this equation: a=1, b=4, c=-14
1x2+4x+−14=0
x=
−b±√b2−4ac
2a
x=
−(4)±√(4)2−4(1)(−14)
2(1)
x=
−4±√72
2
x=−2+3√2 or x=−2−3√2
Answer:
B - there is a loss of $100
Step-by-step explanation:
Since nothing got sold, your equation becomes 10(0) - 100, or just -100, meaning $100 was lost.

Answer:
12 more
Step-by-step explanation:
y-5= 6+ (x+1)
5+6+1=12
By the way your X is my C. The Pythagorean theorem is a^2+b^2=c^2. A is 12, and b is 16, you would first plug them in. 12^2+16^2=c^2. So then you square them. You would then get 144+256=c^2. So now you add and get 400=c^2. Now find the square root of both sides to get just c. The square root of 400 is 20 and the square root of c^2 is just c. So that means 20=c or in your case x=20.
584 = 8 hours
146 = 2 hours (divide each side by four)
