Answer:
the area of the trapezoid is (8 + 4).3/2 = 18
I’m pretty sure the answer would be A,because if her bill is $97 and it’s $0.10 every txt she sends then and she wants to spend less then $113 then if you take $113 and subtract it by 97 it gives you 16 then if you divided 16/ 0.10 then it gives you 160 so she is sending atleast 160 txt.
About 390 km because you drive 130 km per hour so 130 times 3 is 390
I think its x^2(18x^2 -9+4x) sorry if I’m wrong
