5.20 gallon paint is requires to paint 25,000 boards.
Step-by-step explanation:
First of all we have to make the units same for all the data so,
25,000 boards = 300000 sq inch
Noe,
1 gallon paint covers = 57600 sq inch
gallon paint covers = 300000 sq inch
5.20 gallon paint covers = 300000 sq inch
Hence,
5.20 gallon paint is required to paint the 25000 boards ( 300000 sq inch)
Lets factor first to see if we can make the problem simple
2(4x^2-25)
now we see that in parenthesis we have 2 square numbers
4x^2=(2x)^2
25=(5)^2
our expression is now
2(2x+5)(2x-5)
Answer:
1. Formula is A2 : A9 = COUNT( A2: A9 ) = 8
2. Formula is SUM( A2: A9 ) = 36
3. Formula is B2 : B9 = COUNT( B2: B9) = 8
4. Formula is MAX( C2: C9) = 5
5. Formula is MIN( C4: C8) = 3
6. Formula is SUM( C5 - C6) = 0
7. Formula is AVERAGE( C2: C9) = 4
Step-by-step explanation: Have a nice day! ✌️
