Answer:
(-10, 2)
Step-by-step explanation:
Compare:
g(x) = (x+10)^2+2
f(x) = (x - h)^2 + k
Matching these up, term by term, we see that h = -10 and k = 2. (h, k) represents the vertex of the parabola f(x) = (x - h)^2 + k.
We conclude that the vertex of this parabola is (-10, 2).
Add up the lengths of the several sides of the polygon.
Examples: The perimeter of a triangle is the sum of the lengths of the 3 sides.
The perimeter of a hexagon is the sum of the lengths of the 6 sides.
And so on.
I highly recommend drawing any polygon whose perimeter you wish to calculate.
X=20
180-77=103
so then simplify (6x-17)=103
6x=120
x=20
Answer:
b
Step-by-step explanation:
The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
Answer:
The area of this triangle is.. 
Step-by-step explanation:
6 x 10 divided by 2 = 30
