Answer:
2.62
Step-by-step explanation:

First, write the square root as exponent.

Move the denominator to the numerator and negate the exponent.

Use log product property.

Use log exponent property.

Substitute values.

Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i
A or c is the correct answer
Answer:
Rectangle: 6x4=24
Right triangles: 6x1/2=3
3x2=6
Step-by-step explanation:
If you separate the trapezoid into two triangles and a rectangle you can find the area of the rectangle (length x width) and then to find the area of both of the triangles on the sides you do (leg x leg /2) but since there are two you can multiply by two again (or just do leg x leg).
Hope that helps!
