there are 18 lions, tigers and bears. If the number of lions is 4 less than 3 times the number of bears and the number of tigers
Harlamova29_29 [7]

bears = x \\ lions = 3x - 4 \\ tigers =  \frac{ 3}{4}x + 3

all you have to do next is add all of them in one equation and equate them to 18

when you find x, replace in each expression to get your answers

What is 125x9 64y12 written as a sum of cubes? (25x3)3 (4y4)3 (5x3)3 (16y4)3 (25x3)3 (8y4)3 (5x3)3 (4y4)3.
babunello [35]

The factorization of \rm 125x^9+64  is \rm (5x^3+4)(25x^6-20x^3+16)  .

<h3>Factorization;</h3>

Factorization is nothing but writing a number as the product of smaller numbers.

Given

Polynomial; \rm 125x^9+64

To find the factorization the polynomial equates the equation with zero following all the steps given below.

Then,

The factor of the polynomial is;

\rm 125x^9+64\\\\125x^9+100x^6+80x^3-100x^6-80x^3+56\\\\5x^3(25x^6-20x^3+16)+4(25x^6-20x^3+16)\\\\(5x^3+4)(25x^6-20x^3+16)

Hence, the factorization of \rm 125x^9+64 is  \rm (5x^3+4)(25x^6-20x^3+16) .
