In this case, 7 is being added to the odometer which already reads 78. If you add 7 to 78, you get 85. Meaning y = 85!
B. 4: for x-4
D. -6: for x-6
We know that the area of a square = side ²
Therefore, for a known area A, the side length is
side = √ (area)
= √ (175)
= 13.2288 (to 4 places of decimals).
<span><span>Each time
we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we </span>add
another 180°<span> to the total of the
interior angle.</span></span>
Triangle,
sum interior angle is 180
Square,
is 360
Pentagon is
540
So the
formula is
<span>180 ( n –
2 )</span>
