It doesn't, (-2)2 = 4.
To see this, consider the -2 times table, going down from 3:
-2 x 3 = -6
-2 x 2 = -4
-2 x 1 = -2
-2 x 0 = 0
-2 x-1 = ?
What should the '?' be?
As the multiplier reduces by one, the answer increases by 2, so the next answer will be another increase of 2, ie 0+2=2, and so on:
-2 x-1 = 2
-2 x-2 = 4
-2 x-3 = 6
it doesn't... it equals 4 not -4 because its -2 times-2 and that equals 4
2 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.
A square has 4 equal sides and 4 right angles whereas a rhombus has 4 equal sides but 2 equal acute angles and 2 equal obtuse angles.
square such in e=mc2 2 = square
Not quite because a square has 4 equal sides and 4 equal right angles whereas a rhombus has 4 equal sides but 2 equal opposite obtuse angles and 2 equal opposite acute angles.
Not quite because a square has 4 equal sides and 4 equal right angles whereas a rhombus has 4 equal sides but 2 equal opposite obtuse angles and 2 equal opposite acute angles.
A square is a rectangle. A square is a rectangle with equal sides. A rectangle Has to have 4 right angles (and only 4 corners). A Square has the same definition (4 right angles, and only 4 corners) but all the sides have to be equal. A square is not a rhombus. A rhombus is a parallelogram with equal sides. A parallelogram has to have 4 sides (2 pairs of equal sides.) The equal sides must be parallel. A rhombus has the same definition (4 sides - 2 pairs of equal sides. The equal sides must be parallel.) but all the sides have to be equal lengths.
The numbers are: -4 +square root of 12 and -4 -square root of 12
They both have 4 right angle and have 4 sides but a square has 4 equal sides whereas a rectangle has 2 different equal sides.
a square if it has 2 sets of equal sides, it is a rectangle.
A square has 4 interior right angles whereas a rhombus has 2 equal acute angles and 2 equal obtuse angles
0.4 square miles (o.4 mi^2) = 11,151,360 square feet.
