7x3(5x2+3x+1)=

Answer 1

21(11 +3x) or simplified more, would be: 231 + 63x

Explanation:

P E M D A S

First, Do what is in the parethesis

7 x 3(5 x 2 + 3x + 1)

7 x 3(10 + 1 + 3x)

7 x 3(11 +3x)

Since there are no exponents move on to the next step.

Then multiply.

21(11 + 3x)

I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!

If simplifies even more, it would be

231 + 63x

(If they wanted it to be in simpilest form)
