Hey there!

When they are asking which of them are equal we need to solve a, b, c and d and see if they match up to 6x^2-2x-20.

<u>Starting with A: </u>

Expand:

3 x 2x^2 + 3 x -x + 3 x -6

Simplify 3 x 2x^2 to 6x^2

6x^2 + 3 x -x + 3 x -6

Regroup.

6x^2 = 3x + 3 x -6

Simplify 3 x -6 to -18

6x^2 - 3x - 18

That does not match up to 6x^2-2x-20.

A is INCORRECT.

<u>Solving B:</u>

Collect like terms:

4x - 2x + 2x^2 - 20

The ones bolded are like terms.

So, we now collect them and add them.

4x^2 + 2x^2 = 6x^2

6x^2 - 2x - 20

That matches up with 6x^2-2x-20.

B is CORRECT.

<u>Solving C:</u>

Multiply the parentheses then multiply:

6x^2-12x+10x-20

Collect like terms:

6x^2 - 2x - 20

This matches up with 6x^2-2x-20.

Thus, C is CORRECT.

<u>Solving D:</u>

Multiply the terms in the parentheses by -2:

6x^2 - 2x - 2 x 10

Multiply the numbers:

6x^2 - 2x - 20

This also matches up with 6x^2 - 2x - 20 / they are <u>equal.</u>

Thus, D is also CORRECT.

<h3>Therefore, our answers are: </h3><h2><u>B, C, D </u></h2>

Thanks a ton for using Brainly! :)

WHERE DOES THE PYTHAGOREAN IDENTITY SIN2 Θ + COS2 Θ = 1 COME FROM? HOW WOULD YOU USE IT TO FIND THE SINE COSINE AND TANGENT VALU
Allushta [10]

Imagine a trigonometric circle with radius equal to 1.

We can say that the opposite side of the angle generated by the origin is equal to sen Ф and the adjacent equal to cos Ф


With this we can say that:


h² = c² + c²


If r = 1, then h = 1


1² = cos² + sen²

1 = cos² Ф + sen² Ф


You can use this equation a lot of times because it's the fundamental trigonometric relation
, so, when you something like:


sen Ф = cos Ф + 1


you can take from sen² Ф + cos² Ф = 1 that sen = \sqrt{1 - cos^2} and then resolve.

Help Please<br> A) estimate 49 of 162. <br> B) use mental math to calculate 49 of 162
bija089 [108]
You can round 49 to 50 and you can round 162 to 200.

You know that 5 * 2 = 10, so 50 * 200 must be 1000. You just add the zeroes.
