Answer:
12 mph and 16 mph
Step-by-step explanation:
distance = speed * time
56 = s * 2 + (s - 4) * 2
56 = 2s + 2s - 8
56 = 4s - 8
64 = 4s
16 = s
s = 16
s - 4 = 12
Answer:
Step-by-step explanation:
6 and - 2 are the only two solutions to the required quadratic equation.
So, if the variable is represented by X then (X - 6) and (X + 2) will be the only two factors of the polynomial function.
Therefore, the equation is
(X - 6)(X + 2) = 0
⇒
If the leading coefficient of the equation is 3 then we can write the equation as (Answer)
I think that's correct if yes so please mark me as brainlist and if its wrong so don't report my answer please
BC = 8x
CD = 2x
BD = 10
BC + CD > BD
8x + 2x > 10
10x > 10
x > 1
BC + BD > CD
8x + 10 > 2x
8x - 2x > -10
6x > -10
x > -10/6
BD + CD > BC
10 + 2x > 8x
10 > 6x
x < 10/6
Thus x lies between 1 and 1.6
