A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
I think 15 are orange and 10 are green
Answer:
9x^2-25=(3x-5)(3x+5)
Step-by-step explanation:
9x^2-25=(3x)^2 - 5^2 =(3x-5)(3x+5)
A^2 - B^2 =(A-B)(A+B)
Answer:
<u>It</u><u> </u><u>is</u><u> </u><u>1</u><u>7</u><u>1</u>
Step-by-step explanation:
![{x}^{2} - 3y + x](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%203y%20%2B%20x)
substitute for x and y:
![= {(14)}^{2} - 3(13) + 14 \\ = 196 - 39 + 14 \\ = 171](https://tex.z-dn.net/?f=%20%3D%20%20%7B%2814%29%7D%5E%7B2%7D%20%20-%203%2813%29%20%2B%2014%20%5C%5C%20%20%3D%20196%20-%2039%20%2B%2014%20%5C%5C%20%20%3D%20171)
