Answer:

No real solutions, but there are complex solutions

x=2i and x = -2i.

Step-by-step explanation:

2x² = - 8

x² = - 4

x = +/- √(-4)= +/-√[(-1)*4] = +/-[√4 *√(-1)] = +/- [2*i]

x=2i and x = -2i

Here is a rectangle ABCD.
lana66690 [7]

Answer:

32%

Step-by-step explanation:

Area of rectangle ABCD = 20 * 30 = 600 Sq cm

After increasing the length and width of the rectangle by 20% and 10% respectively.

New length = 30 + 20% of 30 = 30 + 6 = 36 cm

New width = 20 + 10% of 20 = 20 + 2 = 22 cm

Area of new rectangle = 36*22 = 792 Sq cm

Increase in area = 792 - 600 = 192 Sq cm

Percentage increase in area

= (192/600) *100

= 32%

Show Graph with the solution for 2x+3>-9
kicyunya [14]

Answer:

I can't graph on this but x > -6

To graph you should draw a vertical (up and down) dotted line, and shade the graph to the right of the line.

Step-by-step explanation:

2x+3>-9    Subtract 3 from both sides of the inequality.

2x> -12      Divide both sides by 2

x> -6
