Factorise a.x3+4.a.x

Contact [7]

Answer:

${ax}^{3} + 4ax \\$

factorise out a and x :

${ \boxed{answer{= ax( {x}^{2} + 4) }}}\\ but \: farther \: more : \\ = ax( {x}^{2} + {2}^{2} )$

but from general factorization:

${ \boxed{( {a}^{2} + {b}^{2}) = {(a + b)}^{2} - 2ab }}$

a » x

b » 2

therefore:

$= ax \{ {(x + 2)}^{2} - 2(x)(2) \} \\ \\ = { \boxed{ \boxed{ax( {x + 2)}^{2} - 4x }}}$

What are the x and y-intercepts of the line described by the equation?<br> -6x + 3y = 18.9

-BARSIC- [3]

Answer:

x-intercept - x = 1/2y - 3.15

y-intercept - y = 2x + 6.3

Step-by-step explanation:

For x,

-6x + 3y = 18.9

-6x = -3y + 18.9

x = -3y/-6 + 18.9/-6

x = 1/2y - 3.15

For y,

-6x + 3y = 18.9

3y = 6x + 18.9

y = 6x/3 + 18.9/3

y = 2x + 6.3

Rico can walk 3 miles in the same amount of time that Donna can walk 2 miles. Rico walks at a rate 2 miles per hour faster than

tatyana61 [14]

Answer:

$13$

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$
