To find the difference, we are going to destroy the parenthesis first, and then, we are going to perform the operations. Remember that to destroy a parenthesis preceded by a negative sign (-), you should change the signs of the factors inside the parenthesis:


Now we can factor both numerator and denominator and simplify:

We can conclude that the difference in simplest form is:
Answer:1/5
Step-by-step explanation:
20/100=1/5
To get a you have to have a on its own side
56a=7/4
divide 56 on both sides
a=56/1 divided by 4/7 (switch 7/4 to 4/7 because you are going from division to multiplication)
a=32
Hope this helped
The scale factor of a dilation in which the original polygon and its dilated image are congruent is 1.0. If the scale factor is greater than 1, the image is in enlargement. I hope my answer has come to your help. God bless and have a nice day ahead!
