How? (2x^2 - 3x - 4)(x + 7)<br>

lidiya [134]

Answer:

$2 {x}^{3} + 11{x}^{2} - 25x - 28$

Step-by-step explanation:

Using foil method, Multiply the first term

$2 {x}^{2} \times x = 2 {x}^{3}$

Next, Multiply the Outer term in each parenthesis. (2x^2 and 7

$2 {x}^{2} \times 7 = 14 {x}^{2}$

$2 {x}^{2} \times 7 = 14 {x}^{2} \: \: \: 3x \times - x = - 3x$

Then, Multiply the Inner Terms (-3x,-4,7) in each parenthesis

$- 3x \times 7 = - 21x$

$- 4 \times x = - 4x$

Then multiply the last term (-4 and 7).

$- 4 \times 7 = - 28$

Combine it you have

$2 {x}^{3} + 14 {x}^{2} - 3 {x}^{2} - 21x - 4x - 28$

which simplify to

$2 {x}^{3} + 11 {x}^{2} - 25x - 28$

Here is a set of signed numbers: 7, -3, 1/2, -0.8, 0.8, -1/10, -2 Order the numbers from least to greatest. I put the order -1/1

vichka [17]

Answer:

You answer is incorrect. The correct answer is -3, -2, -0.8, -1/10, 1/2, 0.8, 7.

Step-by-step explanation:

-3 is the smallest and 7 is the greatest.

1/2 is 0.5, which is smaller than 0.8.

-1/10 is -0.1, which is greater than -0.8.

-2 is greater than -3.

What is the measure of angle A? What is the measure of angle B?

Anettt [7]

Answer:So, if there is a right angle and it is split into two unequal angles, then you may be able to determine its measurement since one angle is measured. The size of one aspect is thirty-two degrees. Therefore, ninety minus thirty-two is fifty-eight degrees. So, angle b is fifty-eight degrees.
