Answer:
Length: 23.38
Width: 3.34
Step-by-step explanation:
First I drew out a diagram so that I could visibly see the problem. [ a rectangle with 7x on one side and x on the other.
So to find the area you multiply length time width and 7x times x is 7x^2. The actual area is given: 78, so you set that equal to 7x^2.
Then you want to divide by 7 to get 11.14. Then you want to take the square root of 11.14 to get 3.338 which rounds to 3.34 {try not to round until the very end]. This gives you the width of the rectangle, so to find the length you would have to multiply x by 7 to get 23.38. When you multiply the length and width (3.34 x 23.38) you get 78.08 which can round to 78.
7x^2 = 78
x^2 = 78/7
x^2= 11.142...
x = sqrt(1.142...)
x = 3.338 --> 3.34 --> width
3.34 x 7 --> 23.38 --> length
3.34 x 23.38 --> 70.8
Previous balance = $291.96
Payments/credits = $45.00
Unpaid balance = $ 291.96 - $45.00 = $ 246.96
Monthly Interest rate = 1.5 %
Finance charge = 1.5 % of $ 246.96= $3.70
Total balance to be paid when Finance charge is included = $ 246.96 + $3.70= $ 250.66
New purchases = $103.98
New balance = $ 250.66 + $103.98 = $ 354.64
Three feet is equal to one yard!!
The Answer is A because you are multiplying 4 into the a number (x) and 7 in the parentheses
700+60+0 because if you add it all up 700+60+0 it equals 760.
