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

The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.1

Anika [276]

Answer:

0.3 probability that $x \leq -3$

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x <= -3

The values that are -3 or lower are -3 and -5. So

$P(X \leq -3) = P(X = -3) + P(X = -5)$

From the table:

$P(X = -3) = 0.13, P(X = -5) = 0.17$ . So

$P(X \leq -3) = P(X = -3) + P(X = -5) = 0.13 + 0.17 = 0.3$

0.3 probability that $x \leq -3$

For a project, you need to make three triangles out of cardboard. Each triangle has a height of 5 inches and a base of 10 inches

Softa [21]

First, we'll need the area of a single triangle
then we'll multiply that by 3 to get our answer

to find the are of a triangle, we multiply height times base then divide that by 2
so.. 5 x 10 = 50; 50/2 = 25
if 25 = one triangle
then 25 x 3 = 75 = three triangles

answer - 75 sq. in.
