The answer is A. just go by your placements
To complete this problem, we are going to need to use the Pythagorean theorem.
1.find x. as mentioned earlier, we are going to use the Pythagorean theorum (a²+b²=c²). substitute a b and c for the values on the triangle then solve:
x²+3²=5² substitute
x²+9=25
x²=25-9 subtract
x²=14
x≈3.7 solve to the nearest tenth
2. x is about 3.7km. now we need to find y. to do so, we are going to do the same steps that we did to find x:
y²+3²=7²
y²+9=49
y²=49-9
y²=40
y≈6.3
3. now we know all 3 horizontal side lengths so all we need to do to find the total horizontal distance is add the 3 together:
3.7+3+6.3
13
4. after doing all that math we finally got the answer: The plane's total horizontal distance is about 13km.
I hope this was helpful! :)
9x-3x-5-3=2x-12
12x -8 =2x-12
-2x. -2x
10x. -8. =-12
+8. +8
10x. = -4
X = -0.4

Answer:
11.7
Step-by-step explanation:
39.1 - 9.2 = 29.9
29.9 - 18.2 = 11.7
