Answer:

Step-by-step explanation:
Suppose number is x
Following equation can be written from question statement 

Simplifying it further 




 
        
             
        
        
        
The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)
We need to find the expressions that are equivalent to given expression
We solve the expression and check,
A) -30(3 + 2w)
-90 - 60w
Yes it is equivalent.
B) (-9 - 6w)10
-90 - 60w
Yes it is equivalent.
C) -3(30 - 20w)
-90 + 60w
No it is not equivalent.
D)(6 + 4w)15
90 + 60w
No it is not equivalent.
E) -20(4.5 + 3w)
-90 - 60w
Yes it is equivalent.
Therefore, The expression equivalent to the expression -90 - 60w is -30(3 + 2w),  (-9 - 6w)10 and  -20(4.5 + 3w)

Answer:
7) 
Step-by-step explanation:
The pattern is: add two more than you did before: starting from 2.
It would be:
1, 3, 7, 13,  21,  31, 43, 57
 +2 +4 +6 +8 +10  +12  +14
Now use this to answer the questions.
Hope this helped!
Have a nice day!

There is no difference they are both negative numbers or we could say 25 is higher number then 10 but it negative
