vodomira [7]

Step-by-step explanation:

\sqrt{ x^{2}-10x+25}+25+12\sqrt{x} =15\sqrt{x} \\  \\  \therefore \: \sqrt{ x^{2}-10x+ {5}^{2} }+25 =15\sqrt{x} - 12\sqrt{x}\\  \\  \therefore \: \sqrt{( x - 5)^{2}}+25 =3\sqrt{x}  \\  \\ \therefore \:  x - 5+ 25 = 3 \sqrt{x}  \\  \\ \therefore \: x + 20 = 3 \sqrt{x}  \\  \\ squaring \: both \: sides \\ (x + 20)^{2}  = ( {3 \sqrt{x} })^{2}  \\ \therefore \:  {x}^{2}  + 40x + 400 = 9x \\ \therefore \:  {x}^{2}  + 40x + 400  - 9x = 0 \\  \therefore \:  {x}^{2}  + 31x + 400  = 0 \\

I have some homework questions that i am having problems finding. Please help!

[1] There are two main values to science. The first is that mathematics is where we study numbers... and they appear everywhere in the world around us! We see whole numbers when we count, negative numbers when we are in debt (just look at the national debt!), fractions when we share things between people (think pizza, or chocolate bars, yum!), and decimals when we measure distances, lengths, areas, and sizes. In fact, numbers can be used to describe almost anything. Even color can be described as the amount of red, green, and blue light (the RGB system which is how computer screens work). 

The second value to science is the thinking and ideas of mathematics. Mathematics is where we learn the ideas of distance and sizes (such as area and volume). It teaches us to ask, "How far?" or "How big?" These ideas are applied to study geography, biology, astronomy and more. We also learn to look for patterns. In math, these patterns are usually number or geometric patterns, but science applies this idea to discover patterns in the weather, agriculture, oceans, and more.

:)))) solve the following by factorizing: x^2-2x=120
stepladder [879]

Answer:

Step-by-step explanation:

x^2 - 2x = 120\\x^2 - 2x - 120 = 0

We have to find the factors of 120 that can either add up to or have a difference of 2.

The factors of 120 are:

\pm 1, 120, 2, 60, 3, 40, 4, 30, 5, 44, 6, 20, 8, 15, 10, 12...

The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:

(x+10)(x-12)
