Iliana is correct since an integer means a whole number that is not a fraction, which includes negative AND positive numbers. If s=4 than -s is negative (-4) But if we plug in a negative integer, like -5, the negative signs are eliminated and it becomes positive, therefore Alonso is wrong (-s=-(-5)=5) If the question was about a natural number Alonso would have been right since natural numbers are only from 0 and above

Which of the following sets of lengths can Sean use to make a right triangle?
love history [14]

If we know your Pythagorean Triples we can immediately recognize that the last choice is a right triangle:

8² + 15² = 17²

If you don't know your Pythagorean Triples, it's worth learning the first few off the list because teachers use them in problems all the time.  But for now let's just exhaustively check the Pythagorean Theorem for each triangle.  We don't have to multiply everything out; we can analyze the common factors.  If two have a common factor that the third one doesn't have, there's no way for the Pythagorean Theorem to add up.

Clearly 5²+15² is a multiple of 5 but 18² isn't so that one isn't a right triangle.

6²+12² is a multiple of 6, 16² isn't a multiple of 6, not an RT.

15²-5² is a multiple of 5, 13² isn't, no joy.

8²+15² = 64 + 225 = 289 = 17² -- that's a real right triangle, a valid Pythagorean Triple.

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)

What are ALL the true statements.
ale4655 [162]

Answer:

C, E, F

Step-by-step explanation:

A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.

B is a true statement.

C is true because when angles undergo dilations, their "size" does not change.

D is false because dilations do not increase the measures of angles.

E is false because a triangle that underwent a dilation becomes similar, not congruent.

F is true because of E's reasoning.
