AnnZ [28]

Hello!

Let's begin with question 1, 2a(x) · b(x) = ?

2(3x - 1) · $2^{x}$

$2^{x}$ · (6x - 2)

Question 2, a(x) + 2b(x) = ?

3x - 1 + 2( $2^{x}$ )

Question 3, $\frac{b(x)}{2a(x)}$ = ?

$\frac{2^{x}}{2(3x - 1)}$

$\frac{2^{x}}{6x - 2}$

Question 4, 2a(x) + b(x) = ?

2(3x - 1) + $2^{x}$

6x - 2 + $2^{x}$

Question 5, a(x) - b(2x) = ?

3x - 1 - $2^{2x}$
