Answer:
D. 224 inches
Step-by-step explanation:
Length of the new rectangle after dilation = 22 × ⁷/2 = 77 inches
Width of the new rectangle after dilation = 10 × ⁷/2 = 35 inches
Perimeter of rectangle = 2(length + width)
= 2(77 + 35)
= 2(112)
Perimeter = 224 inches

Hello,
The nonagon, polygon with 9 sides, can be divided in 9 triangles which area is
a*c/2
a is the apothem et c the side
Center's angle is 360°/9=40°
as a/14=cos 20°, and (c/2)/14=sin 20°
a*c/2=14*14*sin 20°*cos 20°=14*7*sin40°=98*sin 40°=62,993185...
Area of the nonagon is 9*98*sin 40°=882*sin 40°=566,93867... (in²)
Answer:
y = 2x - 4
Step-by-step explanation:
Can I ask which variable you are solving?
PS I will assume you need the formula y=mx+b
-2x + y = - 4
Here you would translate the m and x variables to the right side making them positive.
y = 2x - 4
Now the formula is in proper form
