Answer:
1. B 2. C
Step-by-step explanation:
1. x^2-18x+(18/2)^2=19+(18/2)^2
(x-18/2)^2=100
(x-9)^2=100
x1= -1 x2= 19
2. x^2=81
x=+-9
x1=-9 x2=9
Answer:
1229 km
Step-by-step explanation:
The missing angle is ...
180° -60° -75° = 45°
Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.
?/sin(75°) = 900 km/sin(45°)
? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km
The UFO is about 1229 km from KA-12.
Answer:
B
Step-by-step explanation:
If it cost $2.05 for each hamburger that's going to be your constant.
And it says plus an additional $2,000 so you will add that after 2.05x.
And it says 13,025 is the total so that would be on the left.
13,025 = 2.05x + 2,000
I'm 100% sure
I took Honors Algebra 1 in 8th grade, so you can trust me!!!
