Answer:
x² - 6x + 9
Step-by-step explanation:
(a - b)² =a² - 2ab + b²
a = x and b = 3
(x - 3)² = x² - 2*x*3 + 3²
= x² - 6x + 9
Answer: The answer is 1,600.
Explanation: since her back yard is a square that means it has 4 sides, and her yard is 400 sq ft. So you multiply 400 by 4 which equals 1,600. I haven’t done this in a long time so I’m not positive. But that should be it.
Answer:
x=2
y=3
Step-by-step explanation:
y=−2x+7
y=5x−7
Set the two equations equal since they are both equal to y
−2x+7
=5x−7
Add 2x to each side
-2x+7+2x = 5x-7+2x
7 = 7x-7
Add 7 to each side
7+7 = 7x-7+7
14 =7x
Divide by 7
14/7 = 7x/7
2 =x
Now find 7
y = 5x-7
y = 5(2) -7
y = 10-7
y = 3
