<h3>Perfect cubes;</h3>
Perfect cubes are the numbers that are the triple product of the same number.
We have to determine
Which monomial is a perfect cube?
A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.
It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.
A perfect cube monomial must have exponents on the variables.
Then
The monomial is a perfect cube is;
![\rm= 343p^6q^{21}r^6\\\\= \sqrt[3]{ 343 }= 7](https://tex.z-dn.net/?f=%5Crm%3D%20343p%5E6q%5E%7B21%7Dr%5E6%5C%5C%5C%5C%3D%20%5Csqrt%5B3%5D%7B%20%20343%20%7D%3D%207)
Hence, the monomial is a perfect cube is

Answer: (4x + 5y)^2
Factor the expression.
3 times the sum of 8 and 4
3(8 + 4) <== ur expression
Answer:
6.2y - 3.7
Step-by-step explanation:
−y+5.3+7.2y−9
Subtract 9 from 5.3 to get −3.7.
−y−3.7+7.2y
Combine −y and 7.2y to get 6.2y.
6.2y−3.7
