Answer:

3rd option

Step-by-step explanation:

8x³ - 27y³ ← is a difference of cubes and factors in general as

a³ - b³ = (a - b)(a² + ab + b²)

8x³ - 27y³

= (2x)³ - (3y)³

= (2x - 3y)((2x)² + 2x(3y) + (3y)²) , that is

= (2x - 3y)(4x² + 6xy + 9y²)

If n represents a number then write an expression for two less than one fourth of n

Ne4ueva [31]

Answer: $\frac{1}{4}n-2$

This is the same as $\frac{n}{4} - 2$ and it is also equivalent to $0.25n-2$

=====================================================

Explanation:

n is some placeholder for a number

one fourth of that number is $\frac{1}{4}n$ which is the same as $\frac{n}{4}$ or $0.25n$ since 1/4 = 0.25

From here, we subtract off 2 to get $\frac{1}{4}n-2$ as one possible final answer.

Find the values of x work 10% of my grade

Ostrovityanka [42]

Answer:

x = 35

Step-by-step explanation:

1. Add all angles

$115+(x+36)+24+(2x+10)+2x$

= $5x+185$

2. Match 360 and fix

$5x+185=360$

$5x=360-185$

$5x=175$

$x=175/5$

$x=35$

Hope this helps
