Answer:
xyz=-3.11
Step-by-step explanation:
X+2x+8X-2y+6y-6y-2z-2z-14z=8+9+11
11x-8y+6y-18z=28
11x-2y-18z=28
xyz(11-2-18)=28
xyz(11-20)=28
xyz(-9)=28
xyz=28/-9
xyz=-3.11
Answer:
x=-6
Step-by-step explanation:
Partially simplified, the equation says 10m + 5m = 10 + 45. Simplified further, it says 15m = 45. At this point, 45 is divided by 15 to isolate the variable. The answer is 3.
TeUpon examination of the dissection of the trapezoid on each side, we can see that we can make out two isosceles triangles on each side. The angle on the corners of the base can be determined by sine function. we can also use pythagorean theorem, in which the other length is equal to 3". This leaves the shorter base equal to 11-2*3 equal to 5"
