) = - 1
y = - x + 3
y - ( - 4) = ( x - 7) ⇔ <em>y = </em>
<em> x + 1 </em>
Answer:
- If the perimeter of a square measures 32 cm, each side measures 32/4= 8 cm, because all sides are equal.
- The diagonal that passes through the center of the square divides the square into two triangles. The triangles are formed by a <u>hypotenuse </u>(the diagonal, which is k in this case), <u>and two sides,</u> that measure 8 cm each, in this case.
- Because of Pythagoras' theorem, we know that the <u>lenght of the hypotenuse</u> (in this case the hypotenuse is k) equals the squared root of the sum of the squared sides, which in this case can be expressed as
.
- Then, k=11.31 cm.
