Answer:

D. 3m^2+m-5

Step-by-step explanation:

A trinomial expression is a polynomial expression with three terms.

The term with the highest power of variable is called the leading term and the co-efficient of this term is called the leading co-efficient.

The alone number without any variable in the expression is called the constant.

Example of a trinomial:

5x^2+2x+4

Leading co-efficient = 5

Constant = 4

A trinomial with a leading coefficient of 3 and a constant term of -5 from the given choices is:

D. 3m^2+m-5

The first element in an arithmetic sequence is 2. Its twenty second is 14. Find the value of n so that a(n)=6
Aleks04 [339]

Answer:

<h2>n = 8</h2>

Step-by-step explanation:

Given the nth term of an arithmetic sequence to be Tn = a+(n-1)d

a = first term of the sequence

n = number of terms

d = common difference.

Given the first element a = 2 and 22nd to be 14

T22 = a+(22-1)d = 14

a+21d = 14

Substtuting a = 2 into the equation to get d

2+21d = 14

21d = 12

d = 12/21

d = 4/7

The nth term of the sequence given a = 2 and d = 4/7 will be expressed as;

Tn = 2+(n-1)4/7

Given Tn = 6

6 = 2+(n-1)4/7

6 = 2+4/7 n - 4/7

6-2+4/7 = 4/7 n

32/7=4/7 n

32 = 4n

n = 32/4

n = 8
