Simplify the polynomial expression given below.<br><br> (2x − 1)(2x2 + 5x + 3) + (3x + 6)

fenix001 [56]

Answer:

$4x^{3}+8x^{2} +4x+3$

Step-by-step explanation:

Hello

To simplify the polynomial we must eliminate the parentheses

by definition

$ax^{n}*bx^{m} =abx^{n+m}$

$(2x-1)(2x^{2} +5x+3)+(3x+6)\\(4x^{3} +10x^{2} +6x-2x^{2} -5x-3)+(3x+6)\\\\We\ add\ the\ similar\ terms\\\\(4x^{3}+8x^{2} +x-3)+(3x+6)\\\\4x^{3}+8x^{2} +4x+3$

I hope it helps

If the ordered pair (a, b) satisfies the inequality. y > x-4, three of these statements are

Mumz [18]

Answer:

If you subtract 4 from a, it will be greater than b

Step-by-step explanation:

Ok, so in order to solve this, it would be easier to substitute (a,b) into the equation:

b>a-4

Ok, next, you just have to work out each individual question to see which one is incorrect. You can immediately know it is the first one, and this is because we know that B is larger in this equation, but the problem says that subtracting 4 from a would be greater than b. This is incorrect, b is greater than 4-a, so the top left would be your answer.

Hope this helps!

Which statement is correct regarding the measurements of the parallelogram? On a coordinate plane, a parallelogram has points (1

spayn [35]

Answer:

Step-by-step explanation:

Let's plot these points (see diagram).

The base is the horizontal length of the parallelogram, while the height is the the perpendicular distance from the top base to the bottom base.

We can see from the graph that the base is 8 units and the height is 3 units. The area of a parallelogram is A = bh, where b is the base and h is the height. Here, the base is 8 and the height is 3, so the area is A = 8 * 3 = 24 square units.

The answer is B.
