Answer:
![x=-1\text{ or }x=11](https://tex.z-dn.net/?f=x%3D-1%5Ctext%7B%20or%20%7Dx%3D11)
Step-by-step explanation:
For
, we have two cases:
![\begin{cases}a=b,\\a=-b\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7Da%3Db%2C%5C%5Ca%3D-b%5Cend%7Bcases%7D)
Therefore, for
, we have the following cases:
![\begin{cases}18=15-3x,\\18=-(15-3x)\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7D18%3D15-3x%2C%5C%5C18%3D-%2815-3x%29%5Cend%7Bcases%7D)
Solving, we have:
.
Therefore,
![\implies \boxed{x=-1\text{ or }x=11}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cboxed%7Bx%3D-1%5Ctext%7B%20or%20%7Dx%3D11%7D)
Answer:
12.5%
Step-by-step explanation:
![\frac{250}{2000} \times 100\%](https://tex.z-dn.net/?f=%20%5Cfrac%7B250%7D%7B2000%7D%20%20%5Ctimes%20100%5C%25)
= 12.5%
Percentage of total cost that is the payments= 12.5%
Answer:
its 10 cuz 240 x 984 = 12009
Step-by-step explanation:
Answer:
A = -10
Step-by-step explanation:
x^2 + 10x + 24 = 0
To find the roots, we need to factor the equation.
What 2 numbers multiply to 24 and add to 10
6*4 = 24
6+4 = 10
(x+6) (x+4)=0
Using the zero product property
x+6 = 0 x+4 = 0
x = -6 x = -4
We want the sum when the roots are added
-6+ -4 = -10
Multiply 3 by 2 and you get six I think
