Where are the expressions you mention?
The given expression 4(3n+2) is equivalent to 12n+8. Either expression gives us the perimeter of the square.

Answer:</h2>
<u>The diameter of circle is </u><u>288.84 units</u>
<h2>
Step-by-step explanation:</h2>
As we know
Circumference of circle = 2*pi*r
where r is radius of the circle
Arranging the equation
C = 2 π r
r = C / 2 π
r = 907.46 / 2 π
r= 144.42
Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units
Step-by-step explanation:
the perimeter is simply the distance you would have to walk when going around the whole object once.
so, you would go a length, a width, another length and another width, until you are finally arriving back at the starting point.
so, the perimeter of a rectangle is
2×length + 2×width = 2×21 × 2×11 = 42 + 22 = 64 m
Answer:
Angle 1 = 41°
Step-by-step explanation:
Since they are both vertical angles
(6x+11)° = (10x-9)°
6x - 10x = -9 - 11
-4x = -20
4x = 20
x= 5.
Therefore,
Angle 1 = 6(5) + 11
Angle 1 = 30 + 11
Angle 1 = 41°
Answer:
Step-by-step explanation:
From the graph in the attachment Y has coordinates:Y(3,2)
The transformation rule for a dilation with a scale factor k about the origin is:
In this case we have 
We substitute the coordinates and to get:
This simplifies to:
The first choice is correct.
