The perimeter of a rectangular pool is 180 yes. The length is 10yds more than the width. Find the length and the width of the po
White raven [17]

Answer:

Width: 85 yards

Length: 95 yards

Step-by-step explanation:

Ok, so we need to make an equation for this problem. Let's call the width, w. We know that the length is 10 more than the width, so we can call it w +10.

180 = w + w + 10

Now, i order to isolate the w's we need to subtract 10 from each side.

170 = 2w

Now, we just have to divide by 2 on both sides.

W = 85

So we now know that the width is 85 and because the length is 10 more, the length is 95 yds.

3 / m + 4 - 4 / m = 6 (i) Show that this equation can be written as 6m^2 + 25m+16= 0
Evgen [1.6K]

Answer:

Proved Below

Step-by-step explanation:

\sf \frac{3}{m+4} - \frac{4}{m} = 6\\LCM = m(m+4)\\Multiplying \ both \ sides \ by\ m(m+4)\\3m - 4(m+4) = 6m(m+4)\\3m-4m-16 = 6m^2+24m\\-m-16 = 6m^2+24m\\Adding\ m\ to\ both\ sides\\-16 = 6m^2+24m+m\\-16 = 6m^2+25m\\Adding \ 16 \ to \ both \ sides\\0 = 6m^2+25m+16\\OR\\6m^2+25m+16 = 0

Hence, Proved that \sf \frac{3}{m+4} - \frac{4}{m} = 6 is equivalent to \sf 6m^2+25m+16 = 0.
