Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
Answer:




Step-by-step explanation:
Required
Find n, x, p and q
n always represent the population surveyed;
So:

x represents the sample from the population
So:

p always represents the given proportion

Solving for q




The value of the pressure is 1 when the value of volume is 10 liters, the correct option is D.
<h3>What is the pressure?</h3>
Pressure is defined as the physical force exerted on an object.
The force applied is perpendicular to the surface of objects per unit area.
Given
The equation is

Where the v is the volume and p is the pressure.
The value of p when the value of volume v is 10 liters is;

Hence, the value of the pressure is 1.
