Answer:
x=-4.73 x=-1.27
Step-by-step explanation:
(x + 3)^2 - 3 = 0
Add 3 to each side
(x + 3)^2 - 3 +3= 0+3
(x + 3)^2 = 3
Take the square root of each side
sqrt((x + 3)^2) =±sqrt( 3)
(x + 3) =±sqrt( 3)
Subtract 3 from each side
x + 3-3 =-3±sqrt( 3)
x = -3±sqrt( 3)
Approximating to 2 decimal places
x=-1.27 x=-4.73
2 × (x + 3) < 5

The function is in fact a polynomial and the degree of the polynomial is 7.
Answer:
<em>500 </em>
<em> </em><em>p </em><em> </em><em>1000</em>
Step-by-step explanation:
Since Andre if giving a rough estimate about how much paper clips are in the box, we will use the (less than or equal to)
Your X value will be your actual number, the equation shows us that p is anywhere between 500 - 1000
The equation looks like this:
26=x*3.5+8.50
where x is the number of pen you bought.
We solve it like this:
first, we subtract 8.50 from both sides:
17.50 =3.5*x
now we divide both sides by 3.5:
5=x
so you purchased 5 pens.
