Answer:

B.) 2(5x-4)(x+1)

Step-by-step explanation:

10x^2+2x-8

= 2(5x^2 + x - 4)

= 2(5x^2 + 5x - 4x - 4)

= 2[5x(x + 1) - 4(x + 1)]

= 2(5x-4)(x+1)

Answer:

B.)  2(5x - 4)(x + 1).

Step-by-step explanation:

10x^2+2x-8

First divide by  the common factor 2:

= 2(5x^2 + x - 4)

Now  we factor the expression in the parentheses using the 'ac' method.

5 * -4 = -20   so to get the  + x in the middle  we need 5x - 4x:

= 2 ( 5x^2 + 5x - 4x - 4)

= 2[ 5x(x + 1) - 4(x + 1)]

= 2(5x - 4)(x + 1)  (answer).

Use the Venn diagram to list the set of elements of A ∩ B in roster form.
artcher [175]

Answer:

A. {e, h}

Step-by-step explanation:

In a Venn diagram, the set of elements in any intersection can simply be visualised. The elements contained in the region where the circles representing different sets overlap, are the set of elements of intersection.

In the Venn diagram given, the set of elements contained in the region where the circles representing A and B overlap are {e, h}.

{e, h} is common to both set A and set B.

Factor 6x4 – 5x2 + 12x2 – 10 by grouping. What is the resulting expression?
lisov135 [29]
Your answer would be the last option, (6x² - 5)(x² + 2).
This is because when you expand it, you get:
6x² × x² = 6x⁴
6x² × 2 = 12x²
-5 × x² = -5x²
-5 × 2 = -10
Which are all the correct terms.

I hope this helps!

Is (-4,4) the solution of the system. 4x+5y>-6 and -2x+7y>20
nikklg [1K]

Answer:

  It is <em>a</em> solution, one of an infinite number of solutions.

Step-by-step explanation:

You can check to see if the given point is in the solution set:

  4(-4) +5(4) = -16 +20 = 4 > -6 . . . . yes

  -2(-4) +7(4) = 8 +28 = 36 > 20 . . . yes

The offered point satisfies both inequalities, so is in the solution set. It is not <em>the</em> solution, but is one of an infinite number of solutions.
