Answer:
The similarity statement: FGHI ~ BCDE
Similarity ratio: 5:1
Step-by-step explanation:
The similarity statement is quite obvious, as there are only two rectangles shown, and the other one is "BCDE".
The similarity ratio is 5:1 because everything in the 1st (FGHI) rectangle is multiplied 5 times the values in the 2nd (BCDE) rectangle.
Answer: 6
Step-by-step explanation: or 9
R= -4
a= -3
using ∑n = a(1-rⁿ)/1-r
∑n:10 = -3(1-(-4)^10)/ 1-(-4)
= -3(1-1,048,576)/1+4
= -3(-1048575)/5
= 3,145,725/ 5
= 629,145
