Answer:
The function to represent the area a of the section inside the border is 
Step-by-step explanation:
Given section inside the border is 
inches and 
inches.
We need to write the function to represent the area of the section inside the border.
We can see the length of border is and width of the border is .
So, the area of the rectangle will be 
The area 
will be
So, the function to represent the area a of the section inside the border is
Answer:

12+8x=44
8x=32
x=4
Answer:
w = 2/9.
Good luck! This Is Correct, BTW
Step-by-step explanation:
We are asked to simply (2√5 + 3√2)². Using formula: (a + b)² = a² + b² + 2ab. Let's say 2√5 = a, 3√2 = b. So,
→ (a + b)² = a² + b² + 2ab
→ (2√5 + 3√2)² = (2√5)² + (3√2)² + 2(2√5)(3√2)
We are aware about the fact that root means 1/2 and square of root means 2/2 that is 1. Using this we get:
→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2√5)(3√2)
Solve the brackets, to do so first put the like terms in one box.
→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2*3)(√5)(√2)
Solve the rest calculations.
→ (2√5 + 3√2)² = 20 + 18 + 2(6)(√10)
→ (2√5 + 3√2)² = 38 + 12√10
Option (a) (38 + 12√10) is the correct option.
