What is the product of (3a + 2)(4a2 – 2a + 9)?

Step-by-step explanation:

Given: We have given two expressions:  (3a + 2) and

We have to find the product of these expressions.

(3a + 2)(

Now we have to use the distributive a(b + c) = a.c + a.c

3a(

=

Now we can combine the like terms and simplify.

=                  [-6a^2 + 8a^2 = 2a^2]

=                                    [27a -4a = 23a]

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

answer:

f(5/2) = 10/3

i hope this you!
