Answer:
344 m^2
Step-by-step explanation:
Area of the 2 triangles: (2)(1/2)(10)(5)=50

294+50=344
B) 7n−3=n+4
In this case, 'n' is used in place of the word 'number'. 'Product' refers to multiplication, so we multiply n by 7. 3 LESS refers to subtraction, so we subtract 3 from 7n. Then, we know that the solution to that is four more than what the actual number is. MORE refers to addition, so we add 4 to n.
