Answer:

Subtract: 5 - 9i = 5-9i  

Add: the result of step No. 1 + (-4) = (5-9i) + (-4) = (5-4) + (-9i) = 1-9i  

Add: the result of step No. 2 + 7i = (1-9i) + 7i = 1 + (-9+7)i = 1-2i

Subtract: 1 - 2i = 1-2i  

Subtract: the result of step No. 1 - 4 = (1-2i) - 4 = (1-4) + (-2i) = -3-2i  

Add: the result of step No. 2 + 7i = (-3-2i) + 7i = -3 + (-2+7)i = -3+5i

Write the sides of GHI in order from shortest to longest
Minchanka [31]

Answer:

IH, GH, IG

Step-by-step explanation:

We will use this key rule: The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

The angle G is 59 degrees, H is 61 degrees and I is 60 degrees.

The smallest angle is 59 degrees, so the shortest side is the one opposite to that angle, which is side IH.

The largest angle is 61 degrees, so the longest side is the side opposite to that angle, which is side IG.

The side in-between these two is side GH, which is opposite to the 60 degree angle.

vekshin1

Answer:

2x+3y=170.......1

1x+5y=225.......2

multiplying equation 2 by 2 and subtracting eq.1 &2

2x+3y-2x-10x=170-225

-7x=-55

x=55/7

55/7+5y=225

5y=225-55/7

y=1520/(7×5)=304/7

Tomtit [17]

Answer:

B

Step-by-step explanation:

The first term of the binomial needs to be multiplied by the entire trinomial. We'll use the distributive property to expand. Now we do the same process for the second term. The last step is to combine the two parts and simplify.
