Answer:
A. 1512
Step-by-step explanation:
Ratio of Volumes = (Ratio of sides)³
V/56 = 3³
V/56 = 27
V = 56 × 27
V = 1512
Cost=3+3

you didn't post any options, so we can't say which is incorrect
The first x coordinate is given by 0 and the second one is given as j. So the length of the base is j. (Sometimes in math they give letters rather than numbers. And since you know it is an isosceles then the other vertex should be at x-coordinate half j or j/2.
Step-by-step explanation:
move the 27 to the other side of the equation like this

use this equation and substitute it into the y value of the first equation
