Answer:

27

Step-by-step explanation:

First you need to find x.

It is shown that DE=EF, so we can use this.

5x-3=3x+7

5x=3x+10

2x=10

x=5

Then, you plug in the value of the variable and solve.

6(5)-3

Find and identify the traces of the quadric surface x2 + y2 − z2 = 36 given the plane. x = k Find the trace. Incorrect: Your ans
AlekseyPX

Answer:

Hyperbola.

Step-by-step explanation:

We start from the function:

x^{2} +y^{2} -z^{2} =36

We may get the traces if we cut the surface in planes x=k. This is equivalent to replace x for k:

k^{2}+y^{2} -z^{2}=36\\y^{2} -z^{2}=36-k^{2}

The last equation is the equation of an hyperbola, which varies its characteristics depending on K (the plane cut).
