Which polynomial does this group of tiles represent? help please!

D) 7x^2 +5x +3

Step-by-step explanation:

So there are 7 ones from ' x^2' and 5 ones from X and 1 + 1 +1

X^2 +x^2+ x^2 + x^2 +x^2+x^2 +x^2+ x+ x+ x+ x +x+1 +1 +1

= 7x^2 +5x +3

Good Luck

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
