110

Step-by-step explanation:

Using the expansion

(a + b)³ = a³ + b³ + 3ab(a + b)

Given

x + = 5 ( cube both sides )

(x + )³ = 5³ = 125 ← expand left side using identity

x³ + + 3(x × )(x + ) = 125

x³ + + 3(1)(5) = 125

x³ + + 15 = 125 ( subtract 15 from both sides )

x³ + = 110

Hope this helps u !!

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

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

simplify the right side:

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

f(5/2) = 10/3

f(5/2) = 10/3
