Area of the triangle:
A = 1/2 · c · b · sin A =
= 1/2 · 30 · 14 · 0.766 ≈ 160.87 ft²
Answer: 160.87 ft²
Answer: 5x - 1 = -6
Step-by-Step Explanation:
We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have <u>5x</u> as a start of the equation. We have <u>-1</u> on the same side as well.
Alright, so on the other side- we have Six symbols of "-1".
That concludes to... <u>-6</u>. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. <u>5x - 1 = -6.</u>

Answer:
8:04 am
Step-by-step explanation:
The first train travels 60 miles from 6am to 7am
So at 7am the trains are 455 - 60 = 395 miles apart
First train: Distance from town A (DA) = Velocity* time = 60t
Second train: Distance from town B (DB) = Velocity*time = 70t
So, DA + DB = 60t + 70t
395 = 130t
t = 395/130
= 3.4 hrs
= 3 hrs 4 mins
The first train left at 5am so the exact time would be 8:04am (5am +3 hrs and 4 minutes)
First you multiply the 2 and the 5 which is 10 then you you multiply the 2 by 3x which is 6x so 4x(10+6x) then you multiply the 4x by the 10 and the 4x by the 6 you should get 40x+24x add those together and you get 64x hope this helped
