Ok so remember
if a+bi is a root, then a-bi is also a root
since 2i is a root, -2i is also a root
use synthetic division and the fact that when we divide by 2i and -2i, we have to get all real coeficients and end witha zero at the end
I will show the division in the attachment
we find m=8
we then find th resulting equation that is x^2-2x+2=0
quadratic formula
x=

x=1+i or 1-i
m=8 and the other roots are
x=-2i, 1+i, 1-i
(B) first calculate the are of the whole rectangle
Then calculate the area of the two triangles . On top right the height will be 5 ft and the base will be 4 ft
And on the bottom left the height will be 4ft and the base will be 10ft
After calculating the area of two triangles and one rectangle
You need to subtract the are of triangles from the area of the rectangle
And what ever comes will be your answer .
I hope you understood the procedure .
Thanks
If you think about slopes it will always be rise over run! Think of rise as climbing a mountain and run as in walking on the mountain you just climbed. In order to find an equation of any problem, you first need to look at a graph for your first clue. See if the line goes straight through the corners of certain places on the graph. If so than you just count rise over run!
In conclusion my thesis or solution for your question would be C.
Answer: The answer is B 0.075 cm
Step-by-step explanation:
Since the drawings is a scale of the original you must use a proportion to solve the desired side. 0.045/.9=w/1.5;w=0.075.
65 % ------------------ 23.4 items
100 % ----------------- x items
65 : 100 = 23.4 : x
65 x = 100 * 23.4
65 x = 2340
x = 2340 : 65
x = 36
Answer: there were 36 items on the test.
