Is the answer to this a, b, c or d?

D

Step-by-step explanation:

This is a 45 45 90 triangle

It is special because the sides are in a certain ratio of 1:1:

is the length of the hypotenuse and 1 is the length of the legs.

This means that the length of the legs are equal, so y=

If 1 part is , we need to find what is.

We can do that with *

6

x=6

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

d is correct
