F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38
The answer is D. because you use Pythagoreans theory and do 12^2+23^2 which equals 673, then you root it and get 26.
Answer: probably D
In math difference means subtraction
Step-by-step explanation:
X^2+10+25=35 if you put all numbers on one side it's:
x^2=35-10-25
x^2=0 square root
x=0
Answer:(
7
,
6
)
Explanation:
We can find the coordinates of the midpoint of a line segment, by finding the mean of the sum of the
x
coordinates and the mean of the sum of the
y
coordinates.
x
=
