Hello :
an equation is : (x+2)² +(y-7)² = 4
x² +4x+4 +y² -14y +49 = 4
x² +4x+y² -14y +49 = 0 ....( answer : 3)
M= 4/6

Answer:
Option B is the correct answer
Step-by-step explanation:
After removing squares with side 4 inch long, the open box will have following dimensions:
Length = x + 9 - 4 - 4 = (x + 1) in
Width = x - 4 - 4 = (x - 8) in
Height = side of square = 4 in
It is given that volume of the open box is 64 cubic inches.

Answer:
Option D. 18.75 cm3
Step-by-step explanation:
we know that
The Boyle's law (Ideal gas law) states that Where temperature remains constant, the pressure is inversely proportional to volume.
so
In this problem we have
P1=150 kPa
P2=200 kPa
V1=25 cm³
substitute and solve for V2
