Answer:
Bank B would pay more interest than Bank A by $0.40
Step-by-step explanation:
1: -60
2: -10
3: 400
4: -15
5: 18
The answer is 76. multiply 15 times 4 which is 60.
and the triangle is the difference of the sides, so 19-15=4.
so then multiply the base and height, this leaves 4x4 which is 16.
then add the two. 60+ 16= 76
