Answer:

A. x = 7, y = 3

Step-by-step explanation:

The triangles are congruent by HL if the hypotenuses are congruent, and if the marked legs are congruent.

3x -1 = 6y +2 . . . . hypotenuses are congruent

2x = 5y -1 . . . . . . .legs are congruent

Subtracting 2 times the first equation from 3 times the second gives ...

3(2x) -2(3x -1) = 3(5y -1) -2(6y +2)

6x -6x +2 = 15y -3 -12y -4

9 = 3y . . . . . . . . . . . add 7 and simplify

y = 3 . . . . . . . . divide by 3

This value of y matches only answer choice A.

Can you have a negative square? Why or Why not?

Inga [223]

Answer:

Yes, you can square a negative number. In fact, any number at all can be squared, even numbers like pi and 0. This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2) (-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
