The answer would be D) 40x^2+65x+25
Hope this helps :)
please make this answer the brainiest it would really help me. thanks :)
The smallest county is 129 square miles large.
Step-by-step explanation:
Let,
Smallest county = x
Largest county = y
According to given statement;
The largest county in the state of Texas is 6064 square miles larger than the smallest county in the same state.
y = x+6064 Eqn 1
The size of the largest county is 48 times the size of the smallest county plus one square mile.
y = 48x+1 Eqn 2
As Eqn 1 and Eqn 2 are both equal to y, therefore,
Eqn 1 = Eqn 2
Dividing both sides by 47
The smallest county is 129 square miles large.

Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17
Answer:
3x^2-20x-7 in^2.
Step-by-step explanation:
The area of the frame = total area - area of the painting.
This is (2x-3)^2-(x+4)^2
= 4x^2-12x+9-(x^2+8x+16)
= 4x^2-12x+9-x^2-8x-16
= 3x^2-20x-7 in^2.
