Find the value of the expression: x(x-y)-y(y^2-x) for x=4 and y=2
1 answer:
Replacing x by 4 and y by 2, it is found that the value of the expression is of 8.
The expression given is:
We want to evaluate it for x=4 and y=2, hence, we replace x by 4 and y by 2, then:
The value of the expression is of 8.

ANSWER
• Circumference: 18.84 ft
,• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,
In this case, the radius is r = 3 ft and we have to use 3.14 for π,
Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,
In this case, r = 3 ft and π = 3.14,
Hence, the area of this circle is 28.26 square feet.
