Question

Need help with 73, 74, 75, & 76. Find the value of X.

Answer 1

288 is the value of x

Answer 2

see explanation

Explanation:

73.

18 = 3x
`√(3)` (divide both sides by 3 )

6 = x
`√(3)` ( multiply both sides by
`√(3)` )

6
`√(3)` = 3x [
`√(3)` ×
`√(3)` = 3 ]

divide both sides by 3

x = 2
`√(3)`

74.

24 = 2x
`√(2)` ( divide both sides by 2 )

12 = x
`√(2)` ( multiply both sides by
`√(2)` )

12
`√(2)` = 2x ( divide both sides by 2 )

x = 6
`√(2)`

75.

9
`√(2)` × x = 18
`√(2)` ( divide both sides by 9
`√(2)` )

x = 2

76.

2 = x ×
`(4)/(√(3) )` ( multiply both sides by
`√(3)` )

2
`√(3)` = 4x ( divide both sides by 4 )

x =
`(√(3) )/(2)`
