Find the value of the expression: a p^2q^2+pq–q^3–p^3 for p=4 and q=−4
1 answer:
Answer:
240
Step-by-step explanation:
To evaluate the expression for specific numerical values, put the numbers in place of the corresponding variables, and do the arithmetic. A calculator or spreadsheet can help you with this.
p^2q^2+pq–q^3–p^3
= 4²(-4)² +4(-4) -(-4)³ -4³
= 4⁴ -4² +4³ -4³
= 4²(4² -1) = 16(15) = 240
The value of the expression is 240.

First, solve the inequality:
Since x is <u>greater than</u> -8, you have the arrow point up the graph towards the positive side starting at -8.
Since it's greater than but not equal to -8, the circle is open.
Thus your graph is D.
