Answer 2

Answer:

the value of x³+ 2(x - 5) + 4 when x = -3 is - 39

Step-by-step explanation:

given equation is :

x³+ 2(x - 5) + 4

value of 'x' is given as (-3)

x = -3

substitute the value of 'x' in the given equation:

x³+ 2(x - 5) + 4

=(-3)³ + 2(-3 - 5) +4

= (-3)(-3)(-3) + 2(-8) +4

= (9)(-3) - 16 +4

= - 27 - 16 + 4

= - (27 + 16) + 4

= - (43) + 4

= -43 + 4

= - 39
