3 x 4 = 12, so 40 % of 30 is 12.
Hi there!
The rectangle would progress from quadrant 1 to quadrant 2 90 degrees, then to quadrant 3 at 180 degrees, then finally quadrant 4 at 270 degrees. The answer is C) Quadrant IV
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
25x^2 - 4
Step-by-step explanation:
and x times an x is x^2 so
25x^2 - 4
Hope you can read that okay
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).
