We need to simplify the expression:

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:
Now,

On simplifying the above expression we get:




So the simplified form of the expression
.
Answer:
$44487
Step-by-step explanation:
If you plug in 10 for t, you are left with the following equation:
. Hope this helps!
Answer:
No I don't agree with their solution; both their answers are wrong.
Correct answer is
.
Step-by-step explanation:
Given:

Now given:
According to Mai
and According to Tyler 
Now we need to find which of them is correct.
So we will solve the given equation we get;

Subtracting both side by 1 we get;

Now Multiplying both side
we get;

Hence both of them are incorrect, correct answer is
.
Answer:
Discriminant = 20
Step-by-step explanation:
We use formula to find the discriminant.
Discriminant (D) = b^2 - 4ac
The given equation is x^2 - 6x + 4 = 0.
Here the value of a = 1, b = -6 and c = 4.
Plug in the given values in the formula, we get
Discriminant (D) = (-6)^2 - 4*1*4
= 36 - 16
Discriminant = 20
Thank you.
<span>if a trip from earth to mars, is 97/186=.52150
and
a trip from earth to venus is 0.2774(now we have to times it by 2 since its a roundtrip),
we get .5548
we can clearly see that .5548>.52150
So roundtrip venus</span>
