Crank
The answer is “c” because the 6% of 5300 is 318 which they gain each year so multiply. 318 x 18 = 5724 + 5300 that they already have is equal to 11,024

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.
