Answer:
Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
Answer:
9
Step-by-step explanation:
24 - 6 = 18 divided by 2 is 9 so a must be 9
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is

total distance of other way is

now, we can that distance is same from both sides
so, we get

now, we can solve for t



now, we can find one way distance

Answer:
32
Step-by-step explanation:
80 x 40 = 3,200
3,200 / 100 = 32
49/100 is equal to .49 in decimal form, and now we just need to add the 4 wholes. This is equal to 4.49
