Hey there!
2x^2 - 5 / x + 9
= 2(-1)^2 - 5/ -1 + 9
= (2(-1)^2 - 5) / (-1 + 9)
= (2(1) - 5) / 8
= (2 - 5) / 8
= -3 / 8
≈ -0.375
Therefore, your answer is:
-3/8 OR -0.375
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT TO EACH OTHER!
Good luck on your assignment & enjoy your day!

Answer:
C. 
Step-by-step explanation:
Height = 4
Length = 6
Breadth = 7
Note : We were asked to find volume of the cuboid
Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.
Step 1
Find the area of the trapezium
Area of a trapezium = 
Step 2
Calculate the volume of the cuboid
Volume of a cuboid =length× breadth × height
In this case , the volume will be our length × Area of a trapezium
V= 6 × 22
V =
So it is asking you to group like term so
x terms can be grouped/added/subtracted to other x terms, but not to x^2 or x^3 terms
x^2 terms to x^2 and so on so
1. 9-3k+5k=
9+(5k-3k)=
9+2k
2. k^2+2k+4k=
k^2+(2k+4k)=
k^2+6k=
He would have a total of: $1639.09
In intrest alone he would've made 1639.09
Step-by-step explanation:
3%= 0.03
- The first thing you do is multiply $1,500 by the %3 (0.03).
- When your done multiplying, you should get 45.
- Then you repeat the process over, two more times. However the numbers will change.
The line is right in the middle of 100 and 110 degrees so the answer should be 105 degrees. This tool is called a protractor. :)
