Pls hrrry latesha justifies whether the expression 4x – 3 is equivalent to 1/2 (4x-6) - 2x(1-3) by letting x=2 in both expressions. which values should latesha compare to justify whether the expressions are equivalent? 2 and 5 5 and 9 5 and 5 9 and 9

 1)     4x-3

4*2-3

The result is 5

 2)    1/2 (4x-6) – 2x(1-3)    

1/2 (4*2-6) – 2*2(1-3) 

  1/2 (2) – 4(-2) 

1+8

The result is 9

 Latesha should compare to justify whether the expressions are equivalent 5 and 9

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
