Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.
B = 105°, a = 12 cm, c = 19 cm (2 points)
A-29.51 cm^2
B-220.23 cm^2
C-114 cm^2
D-110.12 cm^2

after simplifying it i got: -36.25 as my answer. hope that !

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
