Answer:
Step-by-step explanation:
p=2(l+w)
206=2(x+y)
206=2x+2y
x=width, y=length
x+9=y
206=2x+2(x+9)
206=2x+2x+18
206=4x+18
x=47
y=47+9
y=56
Answer:
A, C, E
Step-by-step explanation:
Substitute the x- coordinate of the points into the equation and if the result is equal to the y- coordinate of the point then it is a solution.
A (- 2, 5 )
y = 2² + 1 = 4 + 1 = 5 → (- 2, 5 ) is a solution
B (- 1, 0 )
y = (- 1)² + 1 = 1 + 1 = 2 ≠ 0 ← not a solution
C (1, 2 )
y = 1² + 1 = 1 + 1 = 2 → (1, 2 ) is a solution
D (2, 4 )
y = 2² + 1 = 4 + 1 = 5 ≠ 4 ← not a solution
E (3, 10 )
y = 3² + 1 = 9 + 1 = 10 → (3, 10 ) is a solution

Answer:
False
Step-by-step explanation:
Definition of Tangency : Tangent to a circle is a line that touches the circle at one point, which is known as Tangency.
At the point of Tangency, Tangent to a circle is always perpendicular to the radius.
We are supposed to find The point of tangency of line S to circle A is M
Considering the definition,
The lines S touches the circle at point J not at M
So,The point of tangency of line S to circle A is M is False
So, Option B is correct
Hence The point of tangency of line S to circle A is M is False
Answer:
85
Step-by-step explanation:
x/5 = 67
x=335
(x+y)/6 = 70
(335+y)/6 = 70
335+y=420
y=85
