Answer:
We can decompose a function into sum of fractions as well.
<em>" Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation " . </em>
<em>Ж</em><em> </em>Now first we will write an expression for \dfrac{3}{8}[/tex]
<em> Ж </em>Now the decomposition of 1 is given as:
And in many more ways we can decompose these numbers.

Answer:
97.5
Step-by-step explanation:
Supplementary angles always add up to 180.
180 - 82.5 = 97.5
Answer:
A.
Step-by-step explanation:
C and D do not create any x² terms when doing the multiplications. so, they are out.
B stands for (a+b)×(a-b) = a² - b².
so, that would give us a "-4" at the end and is not fitting to the "+4" term at the end of the original expression.
that leaves us with A.
let's verify :
(4x+2i)(4x-2i)
it follows the same rule as B :
(a+b)(a-b) = a² - b²
a = 4x
b = 2i
you remember, i = sqrt(-1).
so, we get
(4x)² - (2i)² = 16x² - 4×(sqrt(-1))² = 16x² - 4×(-1) = 16x²+4
bingo !
