Answer:
Approximately (2, 1)
See image
Step-by-step explanation:
Rearrange each equation so it is ready to be graphed on an x-y-axis (see image) look for the point where the two lines cross. This is the solution for the system of equations.
A = 1/2 b h where b = 3.4 cm and h = 8 cm
A = 1/2 (3.4)(8)
A = 13.6 cm^2
Answer: 13.6 cm^2
we know that
For a spherical planet of radius r, the volume V and the surface area SA is equal to

The
ratio of these two quantities may be written as

we know


therefore
the answer is

The answer is 14
-18/6 is -3. add that to 17 and you get 14.
