Answer:

The resultant expression is $6 x^3 - 4 x^2 - 8 x - 16$ .

Step-by-step explanation:

The given expression is

$(3x^2+4x+4)(2x-4)$

Using distributive property, the above expression can be written as

$3x^2(2x-4)+4x(2x-4)+4(2x-4)$

$6x^3-12x^2+8x^2-16x+8x-16$

$6 x^3 - 4 x^2 - 8 x - 16$

Therefore the resultant expression is $6 x^3 - 4 x^2 - 8 x - 16$ .

An arithmetic sequence with a thrid term of 8 and constant difference of 5

olga nikolaevna [1]

$\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
d=5\\
a_3=8\\
n=3
\end{cases}
\\\\\\
a_3=a_1+(3-1)5\implies 8=a_1+(2)5\implies 8=a_1+10
\\\\\\
\boxed{-2=a_1}
\\\\\\
a_n=-2+(n-1)5$

Write an expression to represent the product of 6 and the square of a number plus 15.

inn [45]

Answer:

6x² + 15

Step-by-step explanation:

Let the number be x.

"the square of a number"

x²

"the product of 6 and the square of a number"

6x²

"the product of 6 and the square of a number plus 15"

6x² + 15

The coefficient is the number that multiplies the variable, so it is 6.
