How can I make this a perfect square w^2-4w+

1 answer:

8 0

Ax^2+bx+c
if a=1, then
take 1/2 of b and square it

w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2

to make it into perfect squres, add 4

A spider walks on the outside of a box from point A to B to C to D

Nikitich [7]

The path consists of 4 line segments. Each line segment is the hypotenuse of a different right triangle.

length of line segment AB = $\sqrt{2^{2}+5^{2} } =\sqrt{29} =5.39cm$

length of line segment BC = $\sqrt{3^{2}+4^{2} } =\sqrt{25} =5cm$

length of line segment CD = $\sqrt{3^{2}+5^{2} } =\sqrt{34} =5.83cm$

length of line segment DE $=\sqrt{2.5^{2}+3^{2} } } =\sqrt{15.25} =3.91cm$

The total length of the spider's path is about 20.13 cm.
