Answer: The answer is (D) 
Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by

and width of the rectangle is given by

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.
Therefore, perimeter is given by

Thus, the correct option is (D).
Answer:
1138
Step-by-step explanation:
From the information given:
We can represent it perfectly in an exponential form:

where;
p = initial value = 120
q = base of the exponential form
q = 1 + r
here; r = rate in decimal = 10% = 0.1
Then q can now be = 1 + 0.1 = 1.1
Replacing it into the exponential form, we get:

where;
x = number of days and m = number of shoppers
Thus:
For the first day:

m = 120
For the second day:

m = 132
For the third day:

m = 145.2
For the fourth day

m = 159.72
For the fifth-day

m = 175.692
For the sixth-day

m = 193.2612
For the seventh-day

m = 212.58732
Thus; the total numbers of shoppers for the first 7 days is:

= 1138.46052
≅ 1138

1.4t -0.4(t -3.1) = 5.8 . . . . . . given
1.4t -0.4t +1.24 = 5.8 . . . . . eliminate parentheses
t +1.24 = 5.8 . . . . . . . . . collect terms (now you have a 1-step equation)
