Answer:
D and F
Step-by-step explanation:
can be rewritten as 
.
From there you can use the quadratic formula 
(ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.
Then you get 
Then you get 
So 
Which means 
or 
which are choices D and F.
Answer:
s=5
Step-by-step explanation:
As you can see, you have a whole block that is 20. Then you have another block that is broken down to 4 squares.
So....
4s=20
divide 4 to 4s
divide 4 by 20
so s=5
This is easy, if adding the first number to the second number you get 70.2 then if you want to find the middle number you will have to subtract 32.34 from 70.2 to get 37.86, now add that and 32.34 to check if it gives you 70.2.... When you add them you indeed get 70.2 so your work is correct meaning your middle number is 37.86
Hope this helped
