The difference of two positive numbers is 69. The quotient obtained on dividing one by the other is 4. Find the number.

Answer:

x=92 y=23

Step-by-step explanation:

Let them be x and y respectively

so given

x-y=69

and

x/y=4 x=4y

so we can write

x-y=69

4y-y=69 3y=69 y= 69/3 = 23

now y is 23

so putting in any equation will give the value of x

x-23=69 x=92

CAN SOMEONE MULTIPLY THIS PLEASE, ITS URGENT

Let's factorise it :

$\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) }$

$\: {\qquad \dashrightarrow \sf {x}^{3} (x + 3) + [-5(x + 3)] }$

Using Distributive property we get :

$\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} + ( - 5x - 15) }$

$\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} - 5x - 15 }$

$\: {\qquad \dashrightarrow \sf 4{x}^{3} - 5x - 15 }$

⠀

Therefore,

$\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) =4{x}^{3} - 5x - 15}$
