The factorization of 8x3 – 125 is (2x – 5)(jx2 + kx + 25). What are the values of j and k

Inga [223]

Answer:

$j=4\\k=10$

Step-by-step explanation:

$8x^3 - 125$

$\left(2x\right)^3-5^3$

Use this formula:

$x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)$

Where,

$x=2x\\y=5$

Substitute in the values.

$\left(2x\right)^3-5^3=\left(2x-5\right)\left(2^2x^2+5\cdot \:2x+5^2\right)$

$\left(2x-5\right)\left(4x^2+10x+25\right)$

Divide and simplify 4/7÷(-11/2)

lys-0071 [83]

Answer: $-\frac{8}{77}$

Step-by-step explanation:

$\frac{\frac{4}{7} }{-\frac{11}{2} }$

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

$\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}$

$\frac{4}{7}*-\frac{2}{11}$

$-\frac{8}{77}$

Solve the system of equations<br> -5x+13y+-7<br> 5x+4y=24<br> y=<br> x=

aleksklad [387]

<h3>The value of y is equal to 1.</h3><h3>The value of x is equal to 4.</h3>

Because both equations have a term that will cancel out if they're added together, we're going to add both equations together.

-5x + 5x = 0

13y + 4y = 17y

-7 + 24 = 17

17y = 17

Divide both sides by 17.

y = 1

Now that we have a constant value of y, we can solve for x.

-5x + 13(1) = -7

-5x + 13 = -7

Subtract 13 from both sides.

-5x = -20

Divide both sides by -5.

x = 4
