I didn’t learn this yet but maybe
It would be 3 cm by 4 cm because you just divide the number of feet by 4.
It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
This is the answer of this question
I got 3x^2 + 12x + 4. I recommend you verify my answer, so you have to combine like terms in the first expression then add all the expressions.
