0
Step-by-step explanation:
just put in 5 for x
Answer:
x=-28
Step-by-step explanation:
you multiply the number first
and you calculate
then you move constant to the right
you changes the sign

Are you by any chance referring to football? If you are, it is either a play in which by running or passing the offense moves down the field towards the opponent's endzone 15 yards, or it can be obtained by the defense committing an egregious penalty, such as a facemask, unsportsmanlike conduct, or unnecessary roughness.
As a number, half-gallon can be represented as 0.5.
In order to answer this question we will define each term:
whole numbers are numbers that can be defined as a <span>number without fractions which are greater or equal than 0. E.g. 2 0 1 5 6 85
</span>
integer numbers are numbers that can be defined as a number without fractions but which can be either equal to 0 or greater and lower than 0
E.g. -9 -68 8 0 59
rational numbers are any number that<span> can be expressed as a fraction p/q of two integers E.g. 0.5 = 1/2 1 = 1/1 1.25 = 5/4
</span>
irrational numbers are those which have an approximate value E.g. pi = 3.14...
√2 = 1.41.....
real numbers are all of the above
From all those kind of choices the most accurate representation is rational numbers.
Answer:
x² + 4x + 20 = 12x - 5
x² + 4x - 12x + 20 + 5 = 0
x² - 8x + 25 = 0
Δ = √b² - 4ac
= √(-8)² - 4×1×25
= √64-100
= √(-36)
x ∉ R
