1) Combining like terms, we get x^2 + 5x, which is a binomial.
2) Combining like terms, we get x^3 + 3x^2, which is a binomial.
3) Combining like terms, we get 4x^3 + x^2 - x, which is a trinomial.
4) I can't answer this because there's an asterisk in place of the exponent.
Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.
Let van =v and bus=b
V+6B=324
9V+3B=264×2 this will become
18V+6B=528 minus equ 1 from equ 2
-17V=-204 divide both side by -17
V=-204/-17=12
if V is 12 put it in equ 1
12+6B=324,6B=324-12=312 divide both side by 6
B=312/6=52
therefore the van and bus will take 12 and 52 persons respectively
For this case we have the following function:

To find the distance between the pillars, we must match the equation to zero:

From here, we clear the value of d:

The roots are:
Root 1:

Root 2:
Thus, the pillars are 40 units away.
The maximum height, we obtain it by deriving:

We equal zero and clear d:

Then, we substitute the value of d = 20 in the equation for the height:
The maximum height is 10 units of distance
For this case the ABC arc is given by:
ABC = AB + 41
The arc AB is a straight line, therefore:
AB = 180
Substituting values:
ABC = 180 + 41
ABC = 221 degrees
Answer:
The measure of the ABC arc is given by:
ABC = 221 degrees
