Which expression finds the length of side b of this right triangle?

Step-by-step explanation:

According to the Pythagoras theorem of right triangle,

The square of hypotenuse is the sum of squares of other two sides.

In the given figure ,  c denotes the hypotenuse of the right triangle , a and b are the legs of the triangle.

Then by Pythagoras theorem of right triangle, we have

To find b , first , we subtract from both sodes , we get

Now, take square root on both sides ,we get

Hence, the expression finds the length of side b of this right triangle :

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
