no solution
Step-by-step explanation:
subtract 3 from both sides, and you get that
5x^2=-125
the left side will always be positive because no matter what number you square, it will always be positive. That means there is no solution for this equation

Given:
The original dimensions of a poster are 6 inches by 7 inches.
It is enlarged by a factor of 2.
To find:
The dimensions of enlarged poster.
Solution:
Let the length of the original poster is 6 inches and width is 7 inches.
It is enlarged by a factor of 2. It means, we have to multiply each dimension by 2.
Length of enlarged poster = 2 × 6 inches
= 12 inches
Width of enlarged poster = 2 × 7 inches
= 14 inches
Therefore, the dimensions of enlarged poster are 12 inches by 14 inches.
Note: All options are incorrect.
