No because it would be
if you knew that
ax^2+bx+c was a trinomial square, then the factored form would be
or
so
if w^2-9w+81 is perfect square, factored form is either
or
aka
or
expand them
(x+9)^2=x^2+18x+81, wron middle term
(x-9)^2=x^2-18x+81 wrong
so it is not
Answer:
1. A 2.C
Step-by-step explanation:
Answer:
-15.
Step-by-step explanation:
Arithmetic sequence:-
t2 = a + d
= -19 + 4
= -15.
The answer is A.
The equation simplifies to y=3x+50.
So, C is already not an option.
Now we just plug in points to see if the point works for the equation.
A-11=3(-13)+50
11=-39+50
11=11
Thus, this point falls on the line of this equation and is a point.
So, the answer is A.
I hope this helps!
The radius of a circle is a=pi r^2.
so 360.9=3.14r^2, so that's around 114.94=r^2
r=10.72
