What is the differnce between ║-3║ and - 3.
Deffense [45]

Answer:

l-3l=3 and -3=-3

Step-by-step explanation:

The two bars mean you are finding the absolute value of a number. Absolute value is the distance from zero a number is. Since distance is always positive it basically just means take away the negative if there is one. For example,

l-7l=7 and l8l=8. So the difference is -3 is negative while l-3l is positive.

Solve for x in the equation x2 + 14x+17--96
Veseljchak [2.6K]

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as ax^2+bx+c=0, the by quadratic formula

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

Consider the given equation is

x^2+14x+17=-96

We need to find the value of x.

Add 96 on both sides.

x^2+14x+17+96=-96+96

x^2+14x+113=0

Here, a=1, b=14 and c=113. Using quadratic formula we get

x=\dfrac{-14\pm \sqrt{14^2-4(1)(113)}}{2(1)}

x=\dfrac{-14\pm \sqrt{-256}}{2(1)}

x=\dfrac{-14\pm \sqrt{256}\sqrt{-1}}{2}           (\sqrt{-1}=i)

x=\dfrac{-14\pm 16i}{2}

x=-7\pm 8i

The value of x are x=-7 + 8i and x=-7 - 8i.

Therefore, the correct option is B.

0.2÷ 1 then × both by 100 to change it to 20/100 then simplify by ÷5 which equals 4/20.
31. 4/20 to 1/5

0.24 × 100= 24
1×100 = 100
simplify 24 ÷ 4= 6 then 100÷4= 25
34. 6/25

-0.1 ×100= -10
1×100=. 100
simplify -10÷2=-5 then 100÷ 2= 50
32. -5/50 to -1/10

Just do that for 33, 35 and 36

Which of the following is a factor of f(x) = 3x3 + 8x2 − 87x + 28? (5 points)
N76 [4]

Answer

(x - 4)


Step by step explanation

To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

Here (x - 4) is a factor.

Therefore, x = 4

when we plug in x = 4 in the given expression, we get zero.

Let's check it out.

3(4)^3 + 8 (4)^2 - 87(4) + 28

192 + 128 - 348 + 28

348 - 348

0

The answer is (x - 4)

Thank you.
