Answer 1

Answer:

9/2 = 4.5

Step-by-step explanation:

Given that x=3/2

Substituting the value into 3x(4x-5)

We get,

3×3/2 ( [4×3/2] - 5)

= 9/2 ( 6-5 )

= 9/2 × 1

= 9/2

= 4.5

Answer 2

Answer:

9/2

Step-by-step explanation:

ok so,

as it is given x = 3/2 we will just put it:

=> 3(3/2) (4[3/2]-5)

*May look a bit complex but don't worry.

*opening the brackets:

3 x 3/2 (4 x 3/2 -5)

9/2 (2 x 3- 5) (Here the denominator of 3/2 canceled 4 and so 4 became 2 and the denominator became 1)

9/2 (6-5)

9/2 (1)

9/2 is the answer.
