What is the factored form of this expression? 27m^3 +125n^3

ddd [48]

Answer:

$\left(3m+5n\right)\left(9m^2-15mn+25n^2\right)$

Step-by-step explanation:

$27m^3+125n^3=\left(3m\right)^3+\left(5n\right)^3$

Apply sum of cubes formula: $x^3+y^3=\left(x+y\right)\left(x^2-xy+y^2\right)$

$\left(3m\right)^3+\left(5n\right)^3=\left(3m+5n\right)\left(3^2m^2-3m\times 5n+5^2n^2\right)$

$\left(3m+5n\right)\left(9m^2-15mn+25n^2\right)$

What is the equation in point-slope form of a line that passes through the points (-4, -1) and (5, 7)?

Setler [38]

Answer:

y + 1 = 8/9(x +4)

Step-by-step explanation:

Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9

Using (-4, -1)

y-(-1) = 8/9[x- (-4)]

y + 1 = 8/9(x +4)
