The sequence is geometric and the common ratio is 2
N = {15 +- root of ( 225 + 64) } / 2
= {15 +- root of 289 } / 24
= 15 + 17 } / 2 or { 15 -17 } /2
= 16 or -1
Answer:
The distance between the parallel sides is 20cm.
Step-by-step explanation:
Area of a trapezoid:

where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.
3 of the 4 variables in this equation are already given:
A = 800
a = 48
b = 32
Just plug those in and solve for h:

Answer
24p+ (-31)
Step-by-step explanation:
- P.EM.D.A.S
- 4*6p=24p
- 4*-9=-36
- now it looks like: 1+4+24p+-36
- now for addition 1+4+24p+-36= 24p+ (-31)
