Answer:
Therefore, 1st, 2nd, 3rd and 5th expressions have been written correctly as per description.
Step-by-step explanation:
In this question we have to go through all the statements, which are correct and which are not correct.
The sum of squared and seven time y minus 12
y² + 7y -12 is the correct expression
The difference of the quantity of 8 times the square of x and 5
8x² - 5 is the correct expression
3 times the product of the difference of 2 times y and 1 and the sum of 5 times y and 2
3(2y-1)(5y + 2) is the correct expression
The difference of the equation of 4x and 3 minus 1
(4x - 3) - 1 is the correct expression as per statement
The product of the sum of 3 times x and 2 and the difference of 2 times x and 3
(3x + 2)(2x - 3) is the correct expression
The product of 3 and 5 plus the square of x plus the sum of 14x and 7.
3(5 + x²) + (14x + 7) is the correct expression as per statement
Therefore, 1st, 2nd, 3rd and 5th expressions have been written correctly as per description.
