Which set of side lengths form a right triangle?

1 answer:

8 0

If you have a right triangle, you can use the Pythagorean theorem, which is a²+b²=c². (c is the longest side or the hypotenuse)

You plug in the shorter sides for a and b, then you square root the answer.

A 14m, 20m, 25m

14² + 20² = 25²

196 + 400 = 625

596 = 625 X

B 10cm, 6cm, 8cm

6²+8²=10²

36+64=100

100=100 So your answer is B

X^2-8x+16 divided by ax-4x numerator

Vedmedyk [2.9K]

Answer:

Given:

1). $x^2-8x+16$ divided by $x-4$

⇒ $\frac{x^2-8x+16}{x-4}$

⇒ $\frac{x^2-2\times x\times 4+4^2}{x-4}$

By factorising numerator by using identity, $(a-b)^2=a^2-2\times a \times b +b^2$

⇒ $\frac{(x-4)^2}{x-4}$

⇒ $\frac{(x-4)\times(x-4)}{x-4}$

⇒ $x-4$ {Answer}

2). $3x^2y$ divided by $6xy^2$

⇒ $\frac{3x^2y}{6xy^2}$

⇒ $\frac{3\times x\times x\times y}{6\times x\times y\times y}$

⇒ $\frac{x}{2y}$ { Answer}

There are three declarative statements here. There is no question. We have made up a question to answer.

Another possible answer to the non-question could be, "The parent can ask his student how many students were in the program."
