Gosh, when I saw that my mind went blank
Option 1. 
and option 4.
are equivalent to 
Step-by-step explanation:
Step 1:
The given expression is expanded as follows.
The -2 is multiplied with the 5x and then the -2 is multiplied with the 
.
So the expression becomes as follows;
This is the first option given so the first expression is equivalent.
Step 2:
Of the other four options, only the fourth expression has the fraction 
so the fourth expression is also equivalent.
Expressions 1 and 4 are equivalent to the given expression.
If the width is Wthen the length is 2W-5 W(2W-5)=422W2-5W = 422W2-5W-42 = 0 Factor by grouping or do the quadratic equation.Multiply the coefficient of the squared term.. 2..by the constant ..-42.. 2(-42)=-84Factors of -84 that add to the coefficient..-5.. ofthe W term are 7(-12)Replace the -5W with -12W + 7W 2W2-12W+7W-42 = 02W(W-6) + 7(W-6)=0(2W+7)(W-6)=0
Either: 2W+7 = 0 or W-6 = 0 2W = -7 W = 6 cm W = -7/2 cm
Since W will not be a negative, our width is 6cmThe length is 2W-5 = 2(6)-5=12-5 = 7 cm
