Which is a factor of 2x2y4 − 10x2y + 14y3 − 70?

andrew11 [14]

Answer:

B) x^2y + 7

Step-by-step explanation:

we are given

$2x^2y^4-10x^2y+14y^3-70$

We can use grouping method to factor it

$(2x^2y^4-10x^2y)+(14y^3-70)$

$(2x^2y\times y^3-5\times 2x^2y)+(14y^3-14\times 5)$

now, we can factor common terms

$2x^2y(y^3-5)+14(y^3-5)$

$(y^3-5)(2x^2y+14)$

so, we get

$2x^2y^4-10x^2y+14y^3-70=(y^3-5)(2x^2y+14)$

$2x^2y^4-10x^2y+14y^3-70=(y^3-5)2(x^2y+7)$

$2x^2y^4-10x^2y+14y^3-70=2(y^3-5)(x^2y+7)$

we can see that x^2y+7 is one of factor

John sells candy bars for 2$ each. How much will he make if he sells 10 bars

sertanlavr [38]

Each Candy Bar is $2, so if he sells 10, you just need to multiply,

10 * $2 = 20

So He'll make $20, selling 10 bars.

If he sells 50 bars then just multiply,

50 * $2 = 100

So He'll make $100 selling 50 bars.

Answer:

Answer:C = 8

Answer:C = 8Step-by-step explanation:

-2(4c+16)^1/4+2=-2

Move the constant to the right and change the sign

-2(4c+16)^1/4= -2-2

transform expression

$- 2 \sqrt[4]{4c - 16} = - 4$

Divide each side by -2

$\sqrt[4]{4c - 16 } = 2$

raise both side of the equation by power of 4

4c-16=16

move constant to the right and change the sign

4c=16+16

4c=32

THEN DIVIDE BOTH SIDES BY 4

C = 8
