Answer:
16.2
Step-by-step explanation:
10 squared = 100
19 squared = 361
361 - 100 = 261
square root of 261 = 16.2
is the equation

It’s -1/3 because you subtract 1-5 and -3-9, you get -4/-12 then simplify to get -1/3.
Let's buils the intersection plane:
Point P is on AB and AP=2, then PB=3; point Q is on AE and AQ=1, then QE=4. Let P' be a point on CD such that CP'=2 and Q' be a point on the plane CDHG such that P'Q'=1 and P'Q' is perpendicular to CD. The line CQ' intersects HD at point R and the plane CPQR is intersection plane.
Consider triangles ΔCDR and ΔCP'Q', they are similar. So,
,
so R is a midlepoint of the side HD (for details see picture).
