Well, 9/10 is the same as 9 10ths, the decimal that represents that is 0.9 because it is also 9 10ths
The two numbers are (9+ 5√5)/2 and (9- 5√5)/2.
(9+ 5√5)/2+ (9- 5√5)/2= 9
(9+ 5√5)/2* (9- 5√5)/2= -11
Hope this helps~
Answer:
Option (b) is correct.
The expression is equivalent, but the term is not completely factored.
Step-by-step explanation:
Given : a student factors to
We have to choose the correct statement about from the given options.
Given is factored to
Consider
Using algebraic identity,
comparing and b = 4, we have,
Thus, the factorization is equivalent but we can simplify it further also, as
Using algebraic identity,
Thus,
Can be written as
Thus, the expression is equivalent, but the term is not completely factored.
Option (b) is correct.
Answer:
Step-by-step explanation:
45 - 45 - 90 Triangles
When one leg = x, the hypotenuse = x
So, if the hypotenuse is 1, then divide by to get the leg.
