Answer:

55.93°

Step-by-step explanation:

In this problem, we need to find the cos ratio of x, the ratio of the adjacent side of x to the hypotenuse.

The adjacent side of x is 14 and the hypotenuse is 25.

cos x=14/25=0.56=cos 55.93°

4X^2 - 8X + 4<br> - (2x^2 - 3X + 7 =
kykrilka [37]
I assume the way it's written is like this

4x^2 - 8x + 4 - (2x^2 - 3x + 7)

If that's the case, just combine like terms.

Let's begin with 4x^2. It has the same components as the -2x^2 (remember, since it's being subtracted in the original equation, the number is negative.)

4x^2 - 2x^2 = 2x^2

Now -8x and 3x (be careful, sometimes there's a minus sign in and out of the parentheses, this makes the number positive again

-8x + 3x = -5x

And then 4 and -7

4 - 7 = -3

So the simplified version is finally:

2x^2 - 5x - 3

Hope this helped! If you need me to explain anything, don't be afraid to ask.
