on this point we can use the formula to factor
![v=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D)
where a is 4, b is 12 and c is 9
replacing
![v=\frac{-(12)\pm\sqrt[]{(12)^2-4(4)(9)}}{2(4)}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B-%2812%29%5Cpm%5Csqrt%5B%5D%7B%2812%29%5E2-4%284%29%289%29%7D%7D%7B2%284%29%7D)
and solving
![\begin{gathered} v=\frac{-12\pm\sqrt[]{144-144}}{8} \\ \\ v=\frac{-12\pm\sqrt[]{0}}{8} \\ \\ v=-\frac{12}{8}=-\frac{3}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20v%3D%5Cfrac%7B-12%5Cpm%5Csqrt%5B%5D%7B144-144%7D%7D%7B8%7D%20%5C%5C%20%20%5C%5C%20v%3D%5Cfrac%7B-12%5Cpm%5Csqrt%5B%5D%7B0%7D%7D%7B8%7D%20%5C%5C%20%20%5C%5C%20v%3D-%5Cfrac%7B12%7D%7B8%7D%3D-%5Cfrac%7B3%7D%7B2%7D%20%5Cend%7Bgathered%7D)
The root is
then the polynomial has one root -3/2 if we rewrite the polynomial is
or
If you mean classifying numbers, then I think -35.64 will be a real, rational number
Rational numbers are written as decimals or factions
If a number has a decimal or faction, the number can not be a integer. If its not a integer, then it cannot be a whole number.
Answer:
Steve's lunch is $8.00
Step-by-step explanation:
First you have to make a formula for this almost.
s= Steve's lunch
y= your lunch
s= y-3
s+y-19
then plug in s
y-3+y=19
Then simplify 2y-3=19
Add the three to both sides 2y=22
Divide both sides by 2 y=11
Last plug y into one of your formulas
s=Y-3
s=11-3
s=8
BE SURE TO CHECK YOUR ANSWER S+Y=19 11+8=19 :)
Answer:
$48
Step-by-step explanation:
From the question we know that;
His regular pay is $32 per hour.
Tom worked 48 hours last week and gets time-and-a-half pay for overtime.
Time and a half pay = 1.5
Hence, if Tom works for an hour of overtime, his pay for his overtime is calculated as:
= 1.5 × $32 × 1
= $48
Therefore, he was paid $48 for one hour of overtime.
39 * 39 * 39
59319
It is a cube, all sides are equal distance. If the length is 39 then all the other sides are 39.
