Answer:
If your asking for someone to solve with the work then i believe its -6x
Step-by-step explanation:
I might be wrong so get a second opinion but i think its:
3x(11x-13)
-distribute the 3x to 11x and 13. 3x times 11x is 33x and 3x times 13 is 39x.
Then you get 33x-39x
-subtract. 33x-39x and you get an answer of -6x.
It should be two if this is pre calc.
The width would be 15 in. You divide 1,575 by 5 and by 21 to get 15.
