One polynomial identity that crops up often in various areas is the difference of squares identity:
A2-b2=(a-b) (a+b)
We meet this in the context of rationalising denominators.
6+7 is that good i hope so
It has to be the last one, D. I did it over 3 times to make sure.
#1
Clear shown in graph
#2
No
At. no where graph passes through origin so y intercept is not 0 at anywhere
#3
Domain is x values
#4
Range is y values set
Answer:
the second option : 5 1/3
Step-by-step explanation:
the height (h) in such a right-angled triangle is based on the 2 segments of the baseline : 3 and a
h = 4
the formula is h = sqrt(a×b)
with a and b being the baseline segments.
so,
4 = sqrt(3×a)
16 = 3×a
a = 16/3 = 5 1/3
