Answer:
12.5 and then 6 percent would probably be 12 dollars 80 cents
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
x + (3x - 2) = 18
x + 3x - 2 = 18
4x - 2 = 18
+2 +2
--------------------------
4x = 20
/4 /4
--------------------------
x = 5
Answer:
T=(total cost)
T=1.084x
Step-by-step explanation:
8.4% *x can be rewritten as 0.084x
Then you have 100% of x, the original cost, which is x
x+0.084x= 1.084x
Thus, the total cost is 1.084x
Given:
The volume of the rectangular prism is
![V=4x^3+5x^2-32x-33](https://tex.z-dn.net/?f=V%3D4x%5E3%2B5x%5E2-32x-33)
Two dimensions are (x+1) and (x+3).
To find:
The missing dimension.
Solution:
We know that, volume of a rectangular prism is
![V=length\times breadth\times height](https://tex.z-dn.net/?f=V%3Dlength%5Ctimes%20breadth%5Ctimes%20height)
It means, volume of a rectangular prism is the product of all dimensions.
We have,
![V=4x^3+5x^2-32x-33](https://tex.z-dn.net/?f=V%3D4x%5E3%2B5x%5E2-32x-33)
Splitting the middle terms, we get
![V=4x^3+4x^2+x^2+x-33x-33](https://tex.z-dn.net/?f=V%3D4x%5E3%2B4x%5E2%2Bx%5E2%2Bx-33x-33)
![V=4x^2(x+1)+x(x+1)-33(x+1)](https://tex.z-dn.net/?f=V%3D4x%5E2%28x%2B1%29%2Bx%28x%2B1%29-33%28x%2B1%29)
![V=(x+1)(4x^2+x-33)](https://tex.z-dn.net/?f=V%3D%28x%2B1%29%284x%5E2%2Bx-33%29)
Splitting the middle term, we get
![V=(x+1)(4x^2+12x-11x-33)](https://tex.z-dn.net/?f=V%3D%28x%2B1%29%284x%5E2%2B12x-11x-33%29)
![V=(x+1)(4x(x+3)-11(x+3))](https://tex.z-dn.net/?f=V%3D%28x%2B1%29%284x%28x%2B3%29-11%28x%2B3%29%29)
![V=(x+1)(x+3)(4x-11)](https://tex.z-dn.net/?f=V%3D%28x%2B1%29%28x%2B3%29%284x-11%29)
So, the three dimensions of the rectangular prism are (x+1), (x+3) and (4x-11).
Therefore, the missing dimension is (4x-11).
