Classify the following polynomials according to the number of terms. Combine any like terms first.
11Alexandr11 [23.1K]

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.

What is 5(y-2)-2=2(y+1)-5? Solve for y and show your work please.
Inessa [10]

Answer:

y = 3

Step-by-step explanation:

Let's start with the left side of the equation.

5(y-2)-2= 2(y+1)-5

5y-10-2= 2(y+1)-5

Now let's solve the right side

5y-10-2= 2y+2-5

5y-12= 2y-3

-2y     -2y

3y-12=-3

   +12 +12

3y = 9

3y/3 = 9/3

y = 3

hope this helps!

What is the recursive formula for this sequence? 24,20,16,12
kirza4 [7]

Answer:

28 - 4n

Step-by-step explanation:

What is the recursive formula for this sequence? 24,20,16,12

the sequence first term is 24

a= 24

Common difference (d) = T2 - T1 = T3 - T2

d = 20-24 = 16 -20

d = -4

Formula for nth term

Tn = a + (n-1)d

Tn = 24 + (n -1)-4

Tn = 24 -4n + 4

Tn = 28 - 4n

= 28 - 4n
