In order to eliminate the y terms, the y terms must be reciprocals.
The first equation has 9y.
To eliminate y, you need to add to it -9y.
The second equation has y. In order for the second equation to have -9y, you must multiply both sides of the second equation by -9.
Answer: D -9
Answer:
D.
Step-by-step explanation:
area of a square = side^2
area of a cube = 6 x side^2
let the side be a .
6a^2 = 600
=> a^2 = 600/6
=> a^2 = 100
Hence the area of one of its faces is 100 square inches.
or in plain terms without using those formulas,
6 faces of the cube have 600 square inches
=> 1 face of the cube has 600/6 = 100 square inches
Given:
The given quadratic equation is
