Answer: What is the measure of ∠ DAB?
And we get that the measure of angle is 32 degrees.
Step-by-step explanation:
Let s = northbound train
Then
2s = southbound train
:
Distance = time * speed
4s + 4(2s) = 600
:
4s + 8s = 600
:
12s = 600
:
s = 600/12
:
s = 50 mph is the northbound train
Then
2(50) = 100 mph is the southbound train
:
:
Check:
4(50) + 4(100) = 600

Our task here is to find possible factors of <span>x^2 + 27x + 162.
We need to check out possible factors of 162 first. Examples are:
2(81), 3(54), 6(27), 9(18), and so on. Notice that 9 and 18 add up to 27, so that the factors (x+9) and (x+18) produce x^2 + 27x + 162 when mult. together.</span>
