To simplify an equation like this you must factor out the binomial equation and proceed in cancellation of the same equation.
1. (x-3)/(x-3)(x-4) answer is (x-4)
2.the simplified form after the cancellation is 1/(x-2)(x+4)
3.y+x
4.2x-1/x
I hope i answered your questions correctly

A balloon has a circumference of 28 in use the circumference to approximate the surface area of the ballon to the nearest square
nikklg [1K]

The surface area of the balloon is 249 in².

<h3>What is the surface area of the balloon ?</h3>

A balloon has the shape of a sphere. The distance round the sphere is equal to the circumference of the sphere.

Circumference of the sphere = 2πr

Where:

  • r = radius
  • π = pi = 22 / 7

Radius - circumference / 2π

28 / ( 2 x 22/7) = 4.45 inches

Surface area of a sphere = 4πr²

4 x 22/7 x 4.45² = 249 in²

Let f(x) = 1/ x-4 and g(x) = 1/x -2, evaluate the following.
musickatia [10]

Step-by-step explanation:

Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.

f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7

g(1/2) = 1/1/2 - 2 = -3/2

f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17

g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9

From the given slopes of the lines, identify whether the two lines are parallel, perpendicular, or neither.
vivado [14]

Answer:

Neither

Step-by-step explanation:

To be parallel the lines have to have the same slope. In this case the slopes are not the same.

To be perpendicular, the lines have to have negative reciprocal slopes.

For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.

So, the lines are no parallel and no perpendicular.
