Question

Pls help, I have no idea what to do

Answer 1

The answer could be 42x^2 yz. 42 time 3 equals 126. When multiplying variables add the exponents, so x^2 times x^2 equals x^4. The width is missing 1 y so you input in the length. And lastly you are missing z. So all-together you get 42x^2 yz

Answer 2

I am pretty sure that it is 42x^2y^3z
