1. Plug in the 3 in all the x’s that are in the equation:
(3)2 + y2 = for x2 + y2
(3)2 - y2 = for x2 - y2
This would get you for both equations..
6 + y2 = for x2 + y2
6 - y2 = for x2 - y2
2. Now let’s plug in the value of y which is -4:
6 + (-4)2 = for x2 + y2
6 - (-4)2 = for x2 + y2
This would get you for both equations...
-2 = x2 + y2
14 = x2 - y2
Hope this helped, have an awesome day!
Hello!
I'm assuming we're simplifying here
to simplify, use the distributive property of multiplication
2 * 3x = 6x
2 * (-5) = -10
6x - 10 is your simplified answer
I hope this helps, and have a nice day!
Answer:
9.18 feet
Step-by-step explanation:
dimensions of whole area = (20 + x)(34 + x)
= 680 + 54x + x^2
where x is the width of the flower bed.
we know that x^2 + 54x + 680 = 1200
x^2 + 54x - 520 = 0
x = 9.18 or x = -63.18
width of flower bed cannot be negative therefore it is width 9.18 feet
As area of a square is (side)^2. Here one side is 5y.so the polynomial best suits for the area of this square is (5y)(5y)=25y^2
