Answer:

C = -10x+3

Step-by-step explanation:

So the simplified version of the main expression is -10x+3. after finding the main expression you just need to simplify the rest of them too.

A. = -10x+9

B. = 8x-9

C. = -10x+3

D. = -10x-3

Now that you simplified all the expressions, you can pick out the one that's the same as the target expression, which is C.

Use the cosine function.

cos x = 2/12
cos x = 0.167

use the inverse of cosine:

x = 80.405

The answer is C.

Hope this helps :)

the area of a square mirror is 256 inches squared. A Rectagular mirror has a width the same as the square mirror`s width.Its len
hjlf
Take the square root of 256 to find the side length of the mirror
√256 =16
the rectangles width is 16, it length is 2 inches longer
16+2 =18 so the length is 18 
to find the area multiply them together
18x16=288
the area is 288 inches² :)

One fifth of a number plus three times the number is equal to twice the number plus 42. What is the number
borishaifa [10]

Equation to find number's value: \frac{1}{5}n + 3n = 2n + 42

Number's value: n = 35


Explanation:

Let n be the unknown number for this problem.

One fifth of a number is the same as \frac{1}{5}n.

Three times the number is the same as 3n.

Twice the number plus 42 is the same as 2n + 42.

So, using the information we've gathered so far, we can create the equation that will provide us with n's value.

Equation: \frac{1}{5}n + 3n = 2n + 42

We can use this equation to find n's value.

You can subtract 2n from both sides to get the equation \frac{1}{5}n + n = 42, which is the same thing as the equation we were using.

Now add n and \frac{1}{5}n together to get 1\frac{1}{5}n.

After you do this, your equation should look like 1\frac{1}{5}n=42.

Now divide both sides by 1\frac{1}{5} to get n's value.

n = 35
