Factor: 8ab - 16ac + 12a
a) 4a(2b - 4c + 3)
b) 4a(2b - 4c + 3a)
c) 4a(2b + 4c + 3)
d) 4a(2b - 4c - 3)

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 !

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
