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.

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

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

Bob and Maria each purchase steak from the butcher. Maria selects a cut that costs $19.98 per pound. Bob’s selection costs $13.9

Sidana [21]

Answer:

Bob is paying more for the actual steak

Step-by-step explanation:

we know that

Maria selects a cut that costs $19.98 per pound (Maria's steak is all meat)

Bob’s selection costs $13.98 per pound (Bob’s cut of beef is 1⁄3 bone and fat)

Bob's cut is 2/3 all meat

Find the unit rate of Bob's cut for all meat

$\frac{13.98}{(2/3)} \frac{\$}{pounds} =20.97\frac{\$}{pounds}$

therefore

$\$20.97> \$19.98$

Bob is paying more for the actual steak
