28 - 18 = 10.
150 x 10 = 1500
So all you've got to do is..
150 x 1500 = ???
You can do the rest lol
I^5 + i^6 + i^7 + i^8
i^11 + i^15
i^26
therefore your answer is:
i^26
1 inch = 2.54 cm
100 cm * (1 inch)/(2.54 cm) = 39.37 inches
Penny is taller
Let x= width
Length= 5x-4
2(x)+2(5x-4)=160
2x+10x-8=160
12x-8=160
+8. +8
12x=168
x=14
width=14
length= 5(14)-4=66
