Which of the following methods would be the easiest to use to solve 12x2 – 48 = 0?
Katarina [22]

\bf \stackrel{\textit{solving for \underline{x}}}{12x^2-48=0\implies 12x^2=48\implies x^2=\cfrac{48}{12}\implies x^2=4} \\\\\\ x=\pm\sqrt{4}\implies x=\pm 2

What is the smallest angle of rotational symmetry for a square
mars1129 [50]

When we rotate a figure and there is no change in the shape of the figure then it has rotational symmetry.

We know that the order of rotation for a square is 4.

Hence, we have \frac{360}{4} =90^{\circ}

Thus, the angle of rotational symmetry of square are

90^{\circ}, 180^{\circ}, 270^{\circ}

Hence, the minimum angle  of rotational symmetry is  90^{\circ}

Therefore, the minimum angle of rotational symmetry for a square is 90 degrees.

Perform the operation. Enter your answer in scientific notation.   9 × 102 − 5.6 × 102 =
Arada [10]

Answer:

1489.2

Step-by-step explanation:

9*102-5.6*102=

102(9+5.6) =

102(9.0+5.6) =

102(14.6) =

102*14.6=

14.6*(100+2) =

(14.6*100+14.6*2) =

(1460+(14+.6) *2) =

1460+(28+1.2) =

1460+(28.0+1.2) =

1460+29.2=

1460.0+

29.2

=1489.2
