This is pretty straight forward.
First the area of a rectangle is given by the product of the length and the width and in this case the area is known.
Second the length is an unknown and since we are doing algebra lets call it x
Finally the width is 4 less than the width which is (x-4) units....x will be in meters and the width is 4 meters less then the length.
Putting it together we have x(x-4) = 117 m^2
then
x^2 - 4x = 117
one could use the solution for the quadratic or one could plug in a few numbers as test for the length
10 by 10 is 100 square meters
10 by 14 is 140 square meters
13 by 9 is 117 square meters....x is 13 and x-4 is 9
I used approximation once I had determined the relationship between the area of the rectangle and the perimeter of the rectangle
Answer:
The questions should be on the top of each question as they come.
Step-by-step explanation:
Answer:
A. 1:3
Step-by-step explanation:
The answer would be A because there are 5 candidates for president and 15 total candidates so the ratio would be 5:15. If you simplified the ratio it would be 1:3 because you divide both sides by 5.
hope this helps!!
