Answer:
Lot C
Step-by-step explanation:
There can’t be one formed because all sides of a triangle add up to 180 but when you add that it adds to 190 there for it will not make a triangle
So, when adding in the 7 and 3 the new equation is:
9{(9x7)+(4x3)+9}
Following pemdas, you have to do parenthesis first. So now the equation is:
9(63+12+9)
Now distribute the 9:
567 + 108 + 81
And finally solve as a normal addition problem:
567 + 108 + 81= 756
So, the answer is 756.
I hope this helps:)
