Simplify the expression: 2( x^3 - 3x^2 + 5x - 7 ) A. 2x^3 + 6x^2 + 10x + 14

B. 2x^3 - 6x^2 + 10x + 14

C. 2x^3 + 6x^2 + 10x - 14

D. 2x^3 + 6x^2 + 10x - 14

=2x^3−6x^2+10x−14

i dont know what choice that is but thats the correct answer

Step-by-step explanation:

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

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

i hope this !
