(8,-9) = 4\cdot \:8+5\left(-9\right)=-13\quad :\quad \mathrm{True}

(-2,-1) = 4\left(-2\right)+5\left(-1\right)=-13\quad :\quad \mathrm{True}

(6,3) = 4\cdot \:6+5\cdot \:3=-13\quad :\quad \mathrm{False}

(-7,4) = 4\left(-7\right)+5\cdot \:4=-13\quad :\quad \mathrm{False}

Help! <br> Find the value of X and simplify completely.
Svetach [21]

Answer:

x = 8√5

Step-by-step explanation:

In the figure attached, there are three right angle triangles.

So, by Pythagoras theorem,

y²+ 4² = z²

y² + 16 = z²------(1)

Similarly x² = 16² + y²--------(2)

and (16 + 4)² = x² + z²

20² = x² + z²-------(3)

Now we put the value of z² from equation 1 to equation 3

20² = x² + y² + 16

x² + y² = 400 - 16

x² + y² = 384

y² = 384 - x²------(4)

Now we put the value of y² from equation 4 to equation 2

x² = 16² + 384 - x²

2x² = 256 + 384

2x² = 640

x² = 320

x = 8√5

Therefore x = 8√5 will be the answer.
