circumference = 2PIr

20*2*3.14 = 40*3.14 = 125.6

The answer is A. 125.6

What is the solution of sqrt x+2-15=-3

antiseptic1488 [7]

Answer:

Step-by-step explanation:

Without brackets, we are not exactly sure what is under the root sign. There are 3 choices.

sqrt(x) + 2 - 15 = - 3

sqrt(x + 2) - 15 = - 3

sqrt(x + 2 - 15) = - 3

I think the middle one is what you intend. If not leave a note.

sqrt(x + 2) - 15 = - 3 Add 15 to both sides.

sqrt(x + 2) - 15+15 = - 3+15 Combine

sqrt(x + 2) = 12 Square both sides

x + 2 = 12^2 Do the right

x + 2 = 144 Subtract 2 from both sides.

x + 2-2 = 144-2

x = 142

Simplify completely quantity 4 x squared minus 32 x plus 48 all over quantity 3 x squared minus 17 x minus 6. (1 point)

Galina-37 [17]

Given rational expression is:

$\frac{(4x^2-32x+48)}{(3x^2-17x-6)}$

Now we can simplify this by factoring as shown below:

$=\frac{4(x^2-8x+12)}{(3x^2-17x-6)}$

$=\frac{4(x-2)\left(x-6\right)}{(3x^2-18x+1x-6)}$

$=\frac{4(x-2)\left(x-6\right)}{3x\left(x-6\right)+1\left(x-6\right)}$

$=\frac{4(x-2)\left(x-6\right)}{(3x+1)\left(x-6\right)}$

$=\frac{4(x-2)}{(3x+1)}$

Hence final answer is $\frac{4(x-2)}{(3x+1)}$
