C
15 novelty eraser and a profit of $7
It means that x=15 and y=7
=> C and D is correct
Sold 25 erasers and a profit of $15
It means that x=25 and y=15
=> only C is right.
The sum is ![p^3 -8p^2-17p](https://tex.z-dn.net/?f=p%5E3%20-8p%5E2-17p)
<em><u>Solution:</u></em>
Given that we have to find the sum
<em><u>Given expression is:</u></em>
![(-3p^3+5p^3-2p) + (-p^3-8p^2-15p)](https://tex.z-dn.net/?f=%28-3p%5E3%2B5p%5E3-2p%29%20%2B%20%28-p%5E3-8p%5E2-15p%29)
We have to add both the expressions
Addition of two polynomials involves combining like terms present in the two polynomials
Like terms are the terms having same variable and same exponent
From given expression,
![(-3p^3+5p^3-2p) + (-p^3-8p^2-15p)](https://tex.z-dn.net/?f=%28-3p%5E3%2B5p%5E3-2p%29%20%2B%20%28-p%5E3-8p%5E2-15p%29)
Remove the parenthesis and add
![-3p^3+5p^3-2p-p^3-8p^2-15p](https://tex.z-dn.net/?f=-3p%5E3%2B5p%5E3-2p-p%5E3-8p%5E2-15p)
Combine the like terms
![-3p^3+5p^3-p^3-8p^2-2p-15p](https://tex.z-dn.net/?f=-3p%5E3%2B5p%5E3-p%5E3-8p%5E2-2p-15p)
Add the like terms
![p^3 -8p^2-17p](https://tex.z-dn.net/?f=p%5E3%20-8p%5E2-17p)
Thus the sum is ![p^3 -8p^2-17p](https://tex.z-dn.net/?f=p%5E3%20-8p%5E2-17p)
Answer:
Slant, tilt, declination, diaganol. There are lots of synonyms just gotta choose wisely. Hope this helped! :)
Step-by-step explanation:
Answer:
3 gallons, 3 quarts
Step-by-step explanation:
There are four quarts in each gallon. 15 quarts is the same as 3(4) + 3 quarts, or 3 gallons, 3 quarts. Note that 16 quarts would be the equivalent of 4 gallons.
There are 11 individuals in total. I can divide 11/4 to get 2 3/4. That means there are two 4-person groups.
