The square of a negative number is twelve more than four times the negative number. Find the number.

Aleks04 [339]

X - the number

$x^2=4x+12 \\
x^2-4x-12=0 \\
x^2-6x+2x-12=0 \\
x(x-6)+2(x-6)=0 \\
(x+2)(x-6)=0 \\
x+2=0 \ \lor \ x-6=0 \\
x=-2 \ \lor \ x=6$

The number is negative, so x=-2.

The number is -2.

The length of the midsegment of a triangle is always half the length of the side it is parallel to true or false

Vladimir [108]

True. The midsegment of a triangle is halfway up the triangle, and since the top half and the full triangle are similar triangles, its dimensions are proportional.

This means half the height will give half the base (midsegment). So the midsegment is always half the length of the side it's parallel to.
