A rectangle has an area of 56 56
square inches and a perimeter of 36
36
inches.

Complete the table and write a system of equations to represent the length and width of the rectangle.

Second equation options are : L+W=36, 2L+2W=36, 2(W multiplication sign W)=56

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
