Sum = 5x

Step-by-step explanation:

Given

1: 5x + 20

2: Opposite of 20

Required

Find their sum

Suppose that a is a number; The opposite of a is -a. So, the opposite of 20 is -20.

Having said that:

The required sum is:

Sum = 5x + 20 + (-20)

Remove bracket

Sum = 5x + 20 -20

Sum = 5x

A computer company makes a rectangular screen with a The dimensions of the computer screen are modeled by diagonal of 20 inches.
Novosadov [1.4K]

Answer:

  x = 16

Step-by-step explanation:

The equation shown can be solved this way.

  x^2 +(x -4)^2 = 20^2

  x^2 +x^2 -8x +16 = 400

  2x^2 -8x -384 = 0

  x^2 -4x -192 = 0

  (x -16)(x +12) = 0

The positive solution is ...

  x = 16

_____

Since this makes use of the Pythagorean theorem, you've probably run across the 3-4-5 triangle. You often find scaled versions of it in algebra and geometry problems. Here, it is scaled by a factor of 4 to give a 12-16-20 triangle as half of the display screen.

The 3-4-5 triple is the only Pythagorean triple that is an arithmetic sequence. So, if the difference in side lengths is 4 and the diagonal is 5×4, you can be pretty certain that x = 4×4 and x-4 = 4×3.

Find x step by step ​
11111nata11111 [884]

Answer:

\frac{4 + (x + 1)}{x + 1}  =  \frac{16}{12}  \\  \\  \frac{5 + x}{x + 1}  =  \frac{16}{12}  \\  \\ 12(5 + x) = 16(x + 1) \\ 60 + 12x = 16x + 16 \\ 4x = 44 \\ x = 11
