So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length

There are no real solutions for this equation. All the solutions are imaginary.
Answer:
A.) -0.015x² + 0.365x + 1.116
Step-by-step explanation:
Using a graphing calculator, the quadratic regression equation obtained for the data in the table is :
General form of a quadratic regression equation :
A + Bx + Cx²
A = 1.115714
Bx = 0.3647x
Cx² = - 0.015x²
Hence, rounding to the appropriate number of decimal places, the quadratic regression equation becomes ;
-0.015x² + 0.365x + 1.116
