Answer 1

The first question's answer is the second choice. The second question's answer is the first choice. The third question's answer is the second choice.

Answer 2

Part 1: $Expand \ 7x(x+4)$ 

$7x*x+7x*4$    $Distribute$ 

$Use \ Product \ Rule$    $x^ax^b=x^a^+^b$ 

$7x^2+7x*4$ 

$7x^2+28x$ 


Part 2: $4x(2x^3-7x^2+x)$ 

$4x*2x^3+4x*-7x^2+4x*x$      $Distribute$ 

$4*2xx^3+4x*-7x^2+4x*x$ 

$Use \ Product \ Rule$    $x^ax^b=x^a^+^b$ 

$4*2x^1^+^3+4x*-7x^2+4x*x$ 

$4*2x^4+4x*-7x^2+4x*x$ 

$8x^4-4*7xx^2+4x*x$   $Gather \ like \ terms$ 

$8x^4-4*7x^1^+^2+4x*x$ 

$8x^4-4*7x^3+4x*x$ 

$8x^4-28x^3+4x*x$ 

$8x^4-28x^3+4x^2$


Part 3: $The \ largest \ number \ that \ divides \ evenly \ into \ 12x \ and \ 20 \ is \ 4.$ 

$GCF = 4$
