Answer:
114 in²
Step-by-step explanation:
<h3>Formula provided:</h3>
A = s²
<h3>
Working:</h3>
A = s²
= 12²
= <u>144 in²</u>
75
25 multiplied by 3 is 75
8x^2+5x=-3
8x^2+5x+3=0
after solving this u will get x= (- 5(⁺ ⁻)√-71)/16
The difference between the polynomials is 7y² + 8xy - 3
Polynomials are functions that have a degree of <u>power greater than two.</u>

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)
f(x, y) = (7y^2 + 6xy) - (-2xy + 3)
f(x, y) = 7y² + 6xy + 2xy - 3
f(x, y) = 7y² + 8xy - 3
Hence the difference between the polynomials is 7y² + 8xy - 3
