Answer:
i think the answer is 15x^2+25x+10.
Step-by-step explanation:
what i did was multiply the four sections individually, then add them together.
the top left is 3x*5, which is 15x. top right is 3x*5x, which is 15x^2. this narrows down to answer choice 1 and 3.
red guy is 5*2, which is 10 and the green dude is 2*5x, which is 10x.
add your like terms (15x & 10x) to get 25x...
and there's your answer, 15x^2+25x+10!
hope this helped, i'm really sorry if it's wrong.. :(
