Every rational number is an integer.

True

False

Explanation:

A counter-example could be something like 2/3 which is rational, but not an integer since 2/3 = 0.67  has a fractional or decimal portion to it. An integer is one where its a positive or negative whole number. Zero is also an integer.

Any rational number is a ratio or fraction of two integers. Zero is not allowed in the denominator. Any integer is a rational number since x = x/1, where x is any integer. For example, 9 = 9/1.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
