Step-by-step explanation:

x^2 -100=0

or, (x)^2-(10)^2=0

or, (x+10)(x-10)=0

Either, X+10=0

or, X -10

OR, x-10=0

or, X=+10

Therefore, X= -10 , +10

OR,

X=+-10.

Each good worker can paint my new house alone in 12 hours. Each bad worker can paint my house alone in 36 hours. I need my house
Oduvanchick [21]
In 3 hours, one good worker can paint one fourth of your house. Three good workers can thus paint three fourths of your house in three hours, leaving one fourth to be done by bad workers.

One bad worker can paint one twelfth of your house in 3 hours. There are three twelfths in one fourth, so you will need to hire three bad workers to have your house painted on time.

Do line segments with the given lengths form a right triangle? State whether the line segments with the given lengths form a rig
Dvinal [7]

Given:

19, 180, 181

To be able to determine if the given lengths form a right triangle, the following condition must be met:

\text{ a}^2\text{ + }b^2=c^2

Let's check.

a.) At a = 19, b = 180, c = 181

\begin{gathered} \text{ a}^2\text{ + }b^2=c^2 \\ (19)^2+(180)^2=(181)^2 \\ 361\text{ + 32,400 = 32,761} \\ 32,761\text{ = 32,761} \end{gathered}

Therefore, the given lengths could form a right triangle at a = 19, b = 180 and c = 181.

The answer is yes.

It just happened to be that we got the right answer on the first try, you must also examine at a = 180, b = 181, c = 19 and a = 181, b = 19, c = 180 if the first try didn't meet the right condition.

If you failed to get, then the given lengths could not form a right triangle. The answer would be no.
