Answer:
3 30303/125000
Step-by-step explanation:
![3\times100000 = 3\times10^6 \\ 4\times1000 = 4\times10^3 \\ 2\times10 = 2\times10^1](https://tex.z-dn.net/?f=3%5Ctimes100000%20%3D%203%5Ctimes10%5E6%20%5C%5C%204%5Ctimes1000%20%3D%204%5Ctimes10%5E3%20%5C%5C%202%5Ctimes10%20%3D%202%5Ctimes10%5E1)
So the final statement would be:
Answer : option C, 5x2 + 32x − 21
In the rectangle, the length = 5x - 3 and width = x + 7
We know the formula for area of rectangle = length * width
Area of rectangle = (5x-3)(x+7)
WE multiply it using FOIL method
F - First terms, 5x * x = ![5x^2](https://tex.z-dn.net/?f=%205x%5E2%20)
O- Outer terms, 5x * 7 = 35x
I - Inner terms, -3 * x= -3x
L - Last terms, -3 * 7 = -21
Now we add all the terms
![5x^2 +35x -3x -21](https://tex.z-dn.net/?f=%205x%5E2%20%2B35x%20-3x%20-21%20)
combine like terms
![5x^2 +32x -21](https://tex.z-dn.net/?f=%205x%5E2%20%2B32x%20-21%20)
So area of a rectangle = ![5x^2 +32x -21](https://tex.z-dn.net/?f=%205x%5E2%20%2B32x%20-21%20)
