What is the product of (3a 2)(4a2 Ă˘â‚¬"" 2a 9)? 12a3 Ă˘Ââ€™ 2a 18 12a3 6a 9 12a3 Ă˘Ââ€™ 6a2 23a 18 12a3 2a2 23a 18.

Kay [80]

The product of $(3a + 2)(4a^2 - 2a + 9)$ will be $12a^3 + 2a^2 + 23a + 18.$

Given expression,

$(3a + 2)(4a^2 - 2a + 9).$

We have to find the product of $(3a + 2)(4a^2 - 2a + 9).$

Now using distributive property, we get

$3a(4a^2) - 3a(2a) + 3a(9) + 2(4a^2) - 2(2a) + 2(9)$

$12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18$

$12a^3 + 2a^2 + 23a + 18$

Hence the product of $(3a + 2)(4a2 - 2a + 9)$ is $12a^3 + 2a^2 + 23a + 18.$

Thus the correct option is (D). $12a^3 + 2a^2 + 23a + 18.$

Solve each system by elimination:<br> 10x+8y= -18 <br> 8x+8y= -24

diamong [38]

Answer:

Step-by-step explanation:

10x + 8y = -18

-8x - 8y = 24

2x = 6

x = 3

8(3) + 8y = -24

24 + 8y = -24

8y = -48

y = -6

(3, -6)
