SHORT ANSWER: 84cm
Let width = w
Let length = w + 5
The area of a rectangle is found by multiplying its width by length and the problem states that the area is 84 cm2.
(Width)(Length) = 84
(w)(w + 5) = 84
w2 + 5w = 84
w2 + 5w - 84 = 0
(w + 12)(w -7) = 0
w + 12 = 0
w = -12
The width of a rectangle can't be NEGATIVE!!! Forget about that!
w - 7 = 0
w = 7
Now go back to naming the variables and replace the w with 7.
Length = w + 5 = 7 + 5 = 12
Width is 7 cm. Length is 12 cm.
Check it. Is 7 x 12 = 84? Yes.
Answer:
b= 1421/956
Step-by-step explanation:
- 9.14b +0.42 = 9.56b
- 9.56b - 8.3 = 5.91
- 9.56b= 5.91 +<u>8</u><u>.</u><u>3</u>
- 9.56b = 14.21
- Now devide both sides by 9.56
- Your Final answer is: b= 1421/956

The common difference is 12. However, let’s take a look at how we got there!
First take the 2nd term (23) and find the difference from the 1st term (11). The difference is 12.
Repeat this for the remaining terms…
35 - 23 = 12
47 - 35 = 12
59 - 47 = 12
The common difference is 12.
