Answer:

Step-by-step explanation:

To simplify or to write in the form a+bi, you will need multiply the top and bottom by the bottom's conjugate like so:

Keep in mind when multiplying conjugates you only have to multiply first and last.
That is the product of (a+b) and (a-b) is (a+b)(a-b)=a^2-b^2.
(a+b) and (a-b) are conjugates
Let's multiply now:

i^2=-1




Hi.
12=4/5g
12*5=4g
60=4g
60/4=g
g=15.
Answer:

Step-by-step explanation:
From the question we are told that:
Angel of side 
Angel of side 
Length Side 
Generally the equation for Angle of side ST
is mathematically given by
Since Angle in Triangle =180 therefore


Therefore Applying sine rule to get Length of ST x



35 is the answer cuz u do y2- y1 then x2- x1
To order numbers, they need to all be under the form. So let's transform all this numbers to the decimal form.
3/5 = 0.6
-24% = -24/100 = -0.24
√9 = 3 = 3.0 (all integers are decimals with a zero after the decimal point)
-2 = -2.0
1.6 bar = 1.66666666666 (the bar above the 6 represents an endless number of the digit 6)
π² = 9.86........ endless
(4√5)/2 = 4.47...... endless
4(4/5) = 4 + 4/5 = 4 + 0.8 = 4.8
Now that we got all forms under the decimal form, we can order the numbers from least to greatest:
-2.0 < -0.24 < 0.6 < 1.6666 < 4.47 < 4.8 < 9.86 < 3.0
By correspondence, we get:
-2 < -24% < 3/5 < 1.6 bar < (4√5)/2 < 4(4/5) < π² < 3
Hope this helps! :D
