Answer:
Option C.
Step-by-step explanation:
We need to translate each phrase and find the different expression.
"+" sign is used for sum, more and total.
Twice means two times of a number.
Let n be the unknown number.
Two more than a number = n+2
The total of n and 2 = n+2
Twice the number n = 2n
Sum of n and 2 = n+2
From the above expressions it is clear that only 2n is different from other.
Therefore, the correct option is C.
Answer:
Multiply the first two binomials: (x+2) & (x+4) using the FOIL method (First, Outer, Inner & Last).
(x+2)(x+4) = x^² + 4x + 2x + 8 = x^² + 6x + 8
Then we multiply the trinomial that we got from the first stage and multiply that by the remaining binomial:
(x^² + 6x + 8) (x + 4)
= x^³ + 4x^² + 6x^² + 24x + 8x + 32
Collect the like terms together to give you:
x^³ + 10x^² + 32x + 32
I think this is how you do it: You would multiply 3/8 to 3/4 min...then convert into decimal..and get 0.5 min.
