please answer the question ☺️​

Answer 1

Answer:

-27

Step-by-step explanation:

3×(-20)+3

-60x +3 (x=0.5)

-30+3

-27

Answer 2

3x ( 4x -5) +3

putting the the value of x = 1/2

=> 3× 1/2 ( 4×1/2-5)+3

=> 3/2 ( 2-5)+3

=> 3/2× -3+3

=> -9/2 +3

=> -9+6

2

=> -3/2

hence the value of 3x(4x-5)+3 after putting the value of x = 1/2 ====> -3/2
