Identify the terms and like terms in the expression. a3 + 4 + 2t – 9 + t which statements are true? check all that apply. the expression contains seven terms. the terms in the expression are a3, 4, 2t, 9, and t. the constants, 4 and 9, are like terms. like terms have the same variables to the same powers. a3, 2t, and t are variables, so they are like terms. 2t and t are like terms.

Option (5) 2t and t are like terms is true as both 2t and t are one power term ans thus like terms.

Step-by-step explanation:

 Given expression

Option (1) The expression contains seven terms is wrong as the expression here has five terms namely  A³, 4, 2t, -9, t.

Option (2) The terms in the expression are a³, 4, 2t, 9, and t is false. as the terms in  expression are A³, 4, 2t, -9, t.

Option (3)  The constants, 4 and 9, are like terms is false as Here, constant terms are 4 and -9

Option (4) Like terms have the same variables to the same powers. A³, 2t, and t are variables, so they are like terms. is wrong As A³ is a three power term whereas 2t and t are one power term.

Option (5) 2t and t are like terms is true as both 2t and t are one power term ans thus like terms.

1)The expression  contains only five terms:

2)The constant i.e. 4 and 9 are like terms.

3)Like terms have the same variables to the same powers.

4) 2t and t are like terms .

Step-by-step explanation:

Since we have given that

First we need to simplify the above equation :

so, we can see that there are three terms i.e a, t, constant terms.

The expression  contains only five terms:

The constant i.e. 4 and 9 are like terms.

Like terms have the same variables to the same powers

2t and t are like terms .

the answer is 5636.7
