Answer:
The answer is b. But you asked for the thought process so...
Step-by-step explanation:
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.
We know that
Speed = Distance/Time.
Or, Time = Distance/Speed.
So, the time taken to cover a distance of 50 miles on his first trip = 50/x hr.
And the time taken to cover a distance of 300 miles on his later trip = 300/3x hr.
= 100/x hr.
So we can clearly see that his new time compared with the old time was: twice as much.
Have a great day :)
Answer:
area of the big triangle is QS*RT, where we know the QS
so we need to derive the area of big triange
the big triange is sum of the larger triangle (QT*RT) + smaller one (TS*RT)
so RT*(5+2.2)=RT(5)+RT(2.2)
the rest is simple to solve

Answer:
(x-2)(x-4)
Step-by-step explanation:
First into the X puzzle
8 is on top and 6 is on bottom
Find to number at multiples to 8 and adds to 6
the two numbers are 2 and 4 Then write numbers into factor form
that is (n-2)(n-4)
the factor form should multiples to get F(n)=n²-6n+8
the zeros are 2 and 4 Btw
I hope this helps you
the answer is A because if he lost 10 pounds that is -10 and gained 10 pounds that is +10. -10 + 10= 0
