How do you simplify: 2 radical 50- 3 radical 8

1 answer:

3 0

Let A = 2 radical 50- 3 radical 8
 radical 50 = sqrt( 2* 25 ) = 5sqrt( 2 )
radical 8 = sqrt(2*4) = 2 sqrt(2)
so
A = 2 radical 50- 3 radical 8 = 10sqrt( 2 ) - 6sqrt( 2 ) = 4sqrt( 2 )
finally

A = 4sqrt( 2 )

A NUMBER , TRIPLE THAT NUMBER , AND 12 ARE ADDED THE RESULT IS 32

liraira [26]

If you want to find out what that number is, then let's call it n
n + 3n (Three times the number) + 12 = 32
Simplify
4n + 12 = 32
Subtract 12 from each side
4n = 20
Divide each side by 4
n = 5

Answer:

first method

22=5

7. x

we cross multiply to get

22x= 5×7

22. 22.

x= 35

=1.59

second method

22=5

7. x

we multiply the denominators to get 7x

then we multiply each term by 7x

7x×22 = 5×7x

7. x

here the 7 and 7 will cancel out and the x and x will cancel out to get

22x= 35

22. 22

= 1.59
