The polar form of a complex number is another way to represent a complex number. The form is called the rectangular coordinate form of a complex number. The horizontal axis is the real axis and the vertical axis is the imaginary axis.
It is true because a rational function is defined as those functions where the variable is placed in the denominator, which must be restricted, because all denominators cannot be equal to zero, other wise it would be undetermined
So you have 2 identical big triangles with the h = 5.75 and b = 4:
A=(1/2)bh=(1/2)*4*5.75=11.5
11.5*2=23
Then you have to smaller identical triangles with the h =2 and b=(4+4-4)/2=2
A=(1/2)*2*2=2
2*2=4
Then you have a rectangle:
A=bh=4*2=8
Add all the calculated areas:
A=23+4+8=35
The area of the shape is therefore 35 cm^2
Hope that helped.
Answer:
Step-by-step explanation:
as far as I can tell, is simply asking to write two more expressions, that are equivalent to the provided one, namely, grab the provided one and expand it, if you simplify the expanded version, you'd end up with the provided, for example

so let's do 6a1, 6a3 and 6a5.
