find the area of the metal sheet below that is required to make this square-shaped traffic sign. one side is labeled 8x-1.

solong [7]

Formula for a square is s^2.

(8x-1)^2=

(8x-1)(8x-1)=

64x-8x-8x+1=

64x-16x+1=

48x+1

Therefore, the area of the square mentioned in the question is 48x+1.

The coordinates of Point S are (2/5, 9 1/8). The coordinates of Point T are (-5 7/10, 9 1/8). What is the distance between Point

m_a_m_a [10]

something noteworthy, the y-coordinate for each point is the same, 9⅛, that means is a horizontal line, over which the x-coordinates are at, so since it's a horizontal line, all we need to do is find, what's the distance between $\bf \frac{2}{5}\textit{ and }-5\frac{7}{10}$

of course, let's firstly convert the mixed fraction to improper fraction and then check their difference.

$\bf \stackrel{mixed}{5\frac{7}{10}}\implies \cfrac{5\cdot 10+7}{10}\implies \stackrel{improper}{\cfrac{57}{10}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{2}{5}-\left[-\cfrac{57}{10} \right]\implies \cfrac{2}{5}+\cfrac{57}{10}\implies \stackrel{\textit{using the LCD of 10}}{\cfrac{(2)2+(1)57}{10}}\implies \cfrac{4+57}{10}\implies \cfrac{61}{10}\implies 6\frac{1}{10}$
