5x^2 - ((2x - 3)(2x - 3)) =
5x^2 - (4x^2 - 6x - 6x + 9) =
5x^2 - (4x^2 - 12x + 9) =
5x^2 - 4x^2 + 12x - 9 =
x^2 + 12x - 9 <===

Answer:
Step-by-step explanation:
The latte is what covered the coffee, Caffe latte is a coffee drink made with espresso and steamed milk, and this latte do form heart on the coffee, then we are told that the area of the latte heart is 55cm²
Then, space where latte is not form has a diameter 4cm
Then the radius is diameter divided by 2
r=d/2
r=4/2 =2
Then area of the circle which for the surface for the coffee is πr²
A=πr²
A=3.142×2²
A=12.568cm².
Area of coffee not covered is
55-12.568=42.432cm²
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters
