Answer:

8x^{2} + 3 + -6x

Step-by-step explanation:

First we need to find the like terms so that we could add them. In this case the like terms are,

1. 6x , -2x , -10x

So, these are the only terms that we can add in this expression.

Hence,

=> 8x^{2} + 3 + (6x - 2x - 10x)

=> 8x^{2} + 3 + -6x

And this is as simple as this expression can go until we find the value of "x" which is not yet told.

Hope my answer helped.

If sin(y degrees) = cos(x degrees), which of the following statements is true?
grin007 [14]

Answer:

Angle y and Angle x are complementary angles

Step-by-step explanation:

we know that

If

sin(y°)=cos(x°)

then

Angle y and Angle x are complementary angles

so

∠y+∠x=90°

∠x=90°-∠y

sin(y°)=cos(90°-y°)

therefore

The sine of an angle is equal to the cosine  of its complementary angle

Find the value of x and y
allsm [11]

We have the equations:

x + 3 = 15 and 3y - 1 = 2x - 4

x + 3 = 15    |-3

x = 12

Put the value of x to the second equation:

3y - 1 = 2(12) - 4

3y - 1 = 24 - 4

3y - 1 = 20     |+1

3y = 21    |:3

y = 7


<h3>Answer: x = 12 and y = 7.</h3>
