Answer:

3√3+i3

Step-by-step explanation:

w= 36(cos60°+ isin60°)

√w = w^{1/2}=√36(cos60°+ isin60°)

=6√(cos60°+ isin60°)

now using DeMoivre's theorem

=(cos60°+ isin60°)^{1/2}

=(cos60°/2+ isin60°/2)=(cos30°+ isin30°)

w^{1/2}=6(cos30°+ isin30°)

=6(sqrt3/2+i1/2)\sqrt{frac{3}{2} }

=3√3+i3

If angle ec is a bisector then angles Bec and ced are the same making them both 4x+1. we know a line segment equals 180°. so if we take the 11x-12 and add it to 2(4x+1) we end up with 19x-10=180. you add 10 to both sides and get 19x=190 then you divide by both sides. you'll end up with x=10. you plug In the 10 with aeb and aec and add them together to get 139°. if you're looking for the equation, it's 15x-11.

Use the distributive property to write an expression that is equivalent to 9(c+5).
shepuryov [24]

Answer:

9c + 45

Step-by-step explanation:

The distributive property also known as distributive law of multiplication and division.

In the given expression, distributive law of multiplication is applied where we can multiply first before addition.

Given

9(c+5)

Using distributive property

9(c+5)

= (9 × c) + (9 × 5)

= 9c + 45

9(c+5) = 9c + 45

Please help if you can:)
Minchanka [31]
EXPLANATION:
Let the no. of orders Greg served be x.
Orders Chau served = 2x
Orders Maya served= x + 9
Orders served in all= 69

x + 2x + x + 9 = 69
=> 4x + 9 = 69
=> 4x = 69 - 9
=> x = 60/4
=> x = 15

ANSWER:
Number of orders Maya served = (15 + 9) 24
Number of orders Greg served = 15
Number of orders Chau served = (2*15) 30

Hope it helps u!
