Identify the irrational sum(s). Select all that apply. (more than 1 answer A) √9+ √7
B) 10+ π
C) √16+1/2
D) 2.25+6

A, B

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction for any integers and. Irrational numbers have decimal expansions that neither terminate nor become periodic.

A (bc sqrt7 doesn't terminate)

B (bc pi doesn't terminate)

the others are rational

5x−6

Step-by-step explanation:

Let's simplify step-by-step.

3x+2(x−1)−4

Distribute:

=3x+(2)(x)+(2)(−1)+−4

=3x+2x+−2+−4

Combine Like Terms:

=3x+2x+−2+−4

=(3x+2x)+(−2+−4)

=5x+−6
