Answer:
A)1050
B)8050
Step-by-step explanation:
to find interest we use the formula A= P(1+rt) where P is the initial investment, r is the rate percent, and t is the time interval
for this question we have A=7000(1+3(5)) which gives 8,050 dollars which is the answer to part B
for part A we simply subtract the answer from B from the initial investment so 8050 - 7000 = 1050 made from interest

ax + b= ax + b
Not sure what the length of the rectangle is but to find perimeter of a rectangle you can use the following formula
2w+2l= perimeter
The reason we multiply both the length and width by two is because there are two ends of the width and two ends of the length.
The other formula that would also work is as follows
w+w+l+l= perimeter
Hope it helps
