Answer:
they are equivalent
Step-by-step explanation:
because 4 times 9 is 36 and 4 times 5 is 20 so it is equal to 36+20
The picture is incomplete and the width is missing.
I am going to show you how to do it using any width.
The length shown is x + 4 and the width starts with - x.
Assume the width is - x + a.
Then the area of the rectangle with dimensions x + 4 and - x + a is calculated in this way:
1) given: (x + 4) (- x + a)
2) use distribuitive property: (x)(-x) + (x)(a) + (4)(-x) + (4)(a)
= - x^2 +ax -4x + 4a
3) Combine like terms: - x^2 + (a -4)x + 4a
If the polynomial missing were - x + 7, the answer would be:
- x^2 + (7 -4)x + 4(7) = - x^2 + 3x + 28
With this you are able to get the answer using the real values.

Answer:
I don't have a price of paper near by but I can explain how do it
Step-by-step explanation:
start by puting them in numerical order and tally up how many are under each number. this is going to give you how common each number is on the table. ex: if there is a 2 in every box it would get a 20/20 because it would fill every box. with that you should be able to find where the most common are as well as the rest of the answers. I'm sorry I couldn't help more
18 - [ 18 - [ 18 - ( 18 - 1)]]
= 18 - [ 18 - [ 18 - 17]]
=18 - [ 18 - 1]
= 18 -17
=1
