My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3
I think.
I wanna say the 1st or the last one
Both sides equal each other. Do you want to know how?
√(4 + 16 + 16√3 + 12) = 4√(2 + √3)
Surd Rule: Numbers with the same surd can be added together. Therefore, all whole integers can be added together.
√(4 + 16 + 16√3 + 12)
√((4 + 16 + 12 )+ 16√3 ) =
√(32 + 16√3)
Simplify by Factorising the common factor - 16
√(32 + 16√3) ÷ 16
√(16 (2 + √3))
Square root 16. This is because it is a not a surd because it is not in it's simplest form.
√16 = 4
√4 (2 + √3)
Answer:
x=-5
Step-by-step explanation:
6x+3+10=0
6x+30=0
6x=-30
x=-30/6
x=-5
Use PEMDAS
20 * 20/5 + 100 - 50
Multiply and divide first
20 * 20 = 400
400/5 = 80
Add 100 and then subtract 50
80 + 100 = 180
180 - 50 = 130
130 is the answer.
