hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175
Multiply the numbers
2(2/3)
2/1(2/3)= 4/3 = 1 1/3
Answer:
y=9 and x=18
Step-by-step explanation:
You know that y+3=12 so 12-3=9
You know that x-3=15 so 15+3=18

For the one you put in the comment...
The radius of a circle is 19cm find its area in terms of π
A = π 
A = π 1
A = 361π
For the other one you put in the comment
The radius of a circle is 4 cm find its area in terms of π
A = π 
A = π 
A = 16π
For the other one you put in the comment
The radius of a circle is 20 cm find its area in terms of π
A = π 
A = π 
A = 400π
Hope this helped!
Have a supercalifragilisticexpialidocious day!
