Answer: 16.97
<u>Step-by-step explanation:</u>
To find the distance from W to X, you can use the distance formula ...or... draw a right triangle using W and X as the vertices and use Pythagorean Theorem to find the hypotenuse. I will solve using the latter.
The y-distance from W to X is 12.
The x-distance from W to X is 12.
hypotenuse² = 12² + 12²
= 144 + 144
= 288
hypotenuse = 
= 16.97
Answer:
x < -10.5
Step-by-step explanation:
list the integers that satisfy both these inequalities, 2x+9 <-12
Subtract 9 from both sides;
2x +9 - 9 < -12-9
2x < -21
x < -21/2
x < -10.5
<em>Hence all the integers are values of x less than 10.5</em>

Answer:
-36x^2+1
Step-by-step explanation:
(1+6x)(1-6x)
= 1^2(6x)^2
= -36x^2+1
SOLUTION
At the same time t,
Train 1 would have covered a distance of 80t, since distance = average speed x time.
Train 2 would have covered a distance of 70t.
Now both added should give 210 miles
That is 80t + 70t = 210
150t = 210
t = 210/150
t = 1.4 hours
