2x^2 - 12x + 17
you just simplify it by doing the square number to the bracket and then multiply everything in the bracket by the number outside the bracket (this example 2)
Answer:
A = 413 sq feet
Step-by-step explanation:
The area of the yard = area of rectangle - area of semicircle
The radius of the semicircle, r = 10 feet
The length of the rectangle = 38.5 - 10 = 28.5 feet
So,
The area of the yard = lb - (πr²/2)
![=20\times 28.5-(\dfrac{3.14\times 10^2}{2})\\\\A=413\ ft^2](https://tex.z-dn.net/?f=%3D20%5Ctimes%2028.5-%28%5Cdfrac%7B3.14%5Ctimes%2010%5E2%7D%7B2%7D%29%5C%5C%5C%5CA%3D413%5C%20%20ft%5E2)
So, the required area is equal to 413 sq feet.
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
