please help me

-42

Step-by-step explanation:

Given: x = -5 and y = -3

Solve -y – 3xy

-y – 3xy

-(-3) – 3(-5)(-3)

-(-3) – 3 • 15

-(-3) – 45

3 – 45

-42

I hope this helps

n

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
