Factorise:<br> 8 x 3 + 729 +10800² + 486X.

hjlf

Answer:

(2x+9) ^3

Step-by-step explanation:

(((8 • (x3)) + 729) + (22•33x2)) + 486x

((23x3 + 729) + (22•33x2)) + 486x

Factoring: 8x3+108x2+486x+729

8x3+108x2+486x+729 is a perfect cube which means it is the cube of another polynomial

In our case, the cubic root of 8x3+108x2+486x+729 is 2x+9

Factorization is (2x+9)3

Hope this helped

Find P on AB that is 2/3 of the distance from A(-3,-5) to B(9,4).

Ludmilka [50]

A line segment can be divided into ratios.

<em>The coordinate of P on line segment AB is (5,1)</em>

Given

$A = (-3,-5)$

$B = (9,4)$

The position of P from A to B is:

$P_A = \frac 23$

So, from P to B would be:

$P_B =1 - \frac 23$

$P_B = \frac 13$

So, the ratio is:

$m : n = \frac 23 : \frac 13$

Simplify

$m : n = 2 :1$

<u>The coordinate of point P is:</u>

$P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

So, we have:

$P = (\frac{2 \times 9 + 1 \times -3}{2 + 1},\frac{2 \times 4 + 1 \times -5}{2 + 1})$

$P = (\frac{15}{3},\frac{3}{3})$

$P = (5,1)$

<em>Hence, the coordinate of P is (5,1)</em>
