Which of the statements is true a. v7 is an integer
C. V25 is a rational number
b. V16 is an irrational number
d. 190 is neither rational nor irrational number

The only valid choice is c.

Step-by-step explanation:

Rational Numbers

Rational numbers have the form a/b, where a and b are integers and b is not zero.

In other words, rationals are all numbers that can be written as a fraction.

Examples are -3/7, 11/2, 5, 0

Note the last two numbers are integers, but they are also rationals because an integer can be expressed as a fraction with a denominator of 1.

Irrational numbers are the opposite, they cannot be expressed as a fraction.

a. is not an integer since it's irrational. False

c. = 5 or -5. It is a rational number because it's an integer. True

b. = 4 or -4. It is not an irrational number because it's an integer. False

d. 190 is a rational number. False

The only valid choice is c.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
