Answer:
A.1296
Step-by-step explanation:
Answer:
x=-3/19
y=39/19
Step-by-step explanation:
the equations can be written as the following system

If the second equation is multiplied by 3/2 it will become -18x+3y=9
If that equation is then subtracted with the first you will obtain the following
-19x=3, it means x=-3/19
The other variable is obtained by substituting the new value for x in the first equationx+3y=6, thus we obtain that y=39/19
6a^2x-10 beccause u have to multiply
27/3 = 9 cm3
the pyramid is 1/3 the volume of the cube because it fits exactly inside it
