-5 =(8m+12)/4
multiply each side by 4
-20 = 8m + 12
subtract each side by 12
-32 = 8m
Divide each side by 8
-4 = m
This answer is A: (0,0)

Solution :
It is given that the time required by a company to built the fencing = 4 hours
The length of fenced completed in 1 hour = 1.6 mile
Now by using the double number line to find the length of the fence, we would :
-- We have to draw two parallel straight lines.
-- Let the 1st line represents the time measured in hours and the 2nd line represents the distance or length measured in miles.
-- Mark four marks of equal spacing in both the line so that each mark represents 1 hour in the 1st line and each mark in the 2nd line represents the corresponding lengths.
-- Now in hour, they completed 1.6 miles, therefore from the double number line, we can see that in 4 hours, they completed 4.6 miles of fencing.
Hence the length is 4.6 miles.
Answer:
The side of square A is 30 cm.
Step-by-step explanation:
Given that,
The dimensions of square A are three times the dimensions of square B.
The area of square A is 900 sq cm.
Side of square A = 3( side of square B)
Let the side of square B is b. So,
Side of square A, a = 3b
We know that, the area of square is side². So,
![(3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm](https://tex.z-dn.net/?f=%283b%29%5E2%3D900%5C%5C%5C%5C9b%5E2%3D900%5C%5C%5C%5Cb%5E2%3D100%5C%5C%5C%5Cb%3D10%5C%20cm)
Side of square A, a = 3(10) = 30 cm
Hence, the side of square A is 30 cm.
