Which Expression Is A Sum Of Cubes?

Answers

Answer 1

Answer:

-27a³b⁶ + 8a⁹b¹²

Explanation:

Every term in the expression above every term is a perfect cube.

In the first term (-27a³b⁶), -27 is a perfect cube of -3 while the exponents of a and b are both divisible by three.

In the second term  (8a⁹b¹²),8 is a perfect cube of 2  while the exponents of a and b are divisible by three.

If the index of a number is divisible by three to give a whole number, the result of finding the cube root is a whole number hence a perfect cube root.

Answer 2

Answer:

A) [tex]-27a^{3}b^{6} + 8a^{9}b^{12}[/tex]

Explanation:

-27 can be divided by -3 and the cube root of 8a^9 b^12 is 2a^3 b^4

A town's chamber of commerce printed a map of the buisiness district. The map is 12 inches square, and 1 inch on the map represents an actual distance of 300 feet. On the map, a parking lot for one business is represented by a square with side length 0.25 inches. What is the actual area. In square feet, if the parking lot?

Answers

Answer:

[tex]\boxed{\text{5625 ft}^{2}}}[/tex]

Explanation:

On the map, 300 ft = 1 in

So, for the parking lot

[tex]\text{0.25 in} = \text{0.25 in} \times \dfrac{\text{300 ft}}{\text{1 in}} = \text{75 ft}[/tex]

The formula for the area of a square is

A = l², where l is the length of a side.

A = (75 ft)² = 5625 ft²

[tex]\text{The area of the parking lot is }\boxed{\textbf{5625 ft}^{2}}}[/tex]
