100 + ( 3 + 5 )2 - 5
100 + 16 - 5
116 - 5
111
The first one is 11/5(dilating it with this will make it the same size as the bigger one)
The second on is Translate(translating it will show that they match up perfectly
5(x+3)=3(2x-1)
**distribute
5x+15=6x-3
-5x -5x
**get like term together
15=x-3
+3 +3
**get x alone on one side of the equation
18=x
check your work by replacing the variable x with 18
5(18+3)=3(2·18 -1)
5·21=3·35
105=105 yes!
So, the number you are looking for is 18
Answer:
L = length of arc , R = radius
radian angle = L / R
L = R* radian angle
L = R * 1/3
L = R/3 #1
Area of sector = 1/2 L*R
By substitution using #1
Area of sector = 1/2 * R/3 * R
9 = R^2 /6
R^2= 6*9
R^2= 36
R =✓36
R = 6
Here’s how you can solve Surface Area.
