The length of a rectangle is 6 inches longer than it’s width what are the possible widths if the area of the rectangle is at lea

stealth61 [152]

Let the width = x

length = x + 6

(x + 6) * x = 667

Simplify

x² + 6 = 667

x² + 6 (-6) = 667 (-6)

x² = 661

√x² = √661

x = √661

x = 25.71 (rounded)

25.71 in. is your width

hope this helps

The correct options are

$5x = - 58 \:$ $5x + 4 = - 54$

<h3>How to find same value of x?</h3>

given that

$\frac{5}{6} x + \frac{2}{3} = - 9$

first find value of x to obtain the equations have the same value of x.

Find the L.C.M between the 6,3

$\frac{5x + 4}{6} = - 9$

Then Cross multiplication should be done

$5x + 4 = - 9 \times 6 \\ 5x + 4 = - 54 \\ 5x = - 54 - 4$

$5x = - 58$

Hence the correct options are

$5x = - 58$

$5x + 4 = - 54$
