(3+11i)/(3+11i)=1
So that means you can multiply 6/(3+11i) by (3+11i)/(3+11i)
Then 6(3+11i)/1
= 18+66i
Answer:
Yes
Step-by-step explanation:
the factors of (x^ 2 +9x+20) are (x+4)(x+5)
Answer:
x= - 1.48 or 0.48
Step-by-step explanation:
I used general formula. Hope I'm on a right path.
Answer:
x=10
m=3
Step-by-step explanation:
The angles are the same since the sides are the same length (isosceles triangle)
55 = 5x+5
Subtract 5
55-5 =5x+5-5
50 = 5x
Divide by 5
50/5 = 5x/5
10=x
The altitude is a perpendicular bisector so
5m-3 = 2m+6
Subtract 2m from each side
5m-3-2m = 2m+6-2m
3m-3 = 6
Add 3 to each side
3m-3 +3 =6+3
3m =9
Divide by 3
3m/3 = 9/3
m =3
Answer:
3 books
Step-by-step explanation:
She can carry 3 books in her backpack, this is because 1lb+3lb= 4
and if one book = 2lb each. Then 10-4 =6
so she has 6lb space remaning.
so 6lb divided by 2 = 3
