Area of big rectangle = LxW
=18 x 31
= 558 mm squared
area of small parallelogram= b x h
= 13 x 6
= 78 mm squared
area of shaded part = 558-78=480mm squared
(7x-4y)+( 7x-4y)+(7x-4y)+
(7x-4y)+(7x-4y)
9514 1404 393
Answer:
1,953,125
Step-by-step explanation:
The first term is a1 = 5; the common ratio is r = -25/5 = -5. The generic term is ...
an = a1×r^(n-1)
an = 5×(-5)^(n-1)
So, the 9th term is ...
a9 = 5×(-5)^(9-1) = 1,953,125
I believe this is right:
Least: 8 (length) x 1 (width) = 8
Greatest: 5 (length) x 4 (width) = 20
Difference: 20 - 8 = 12
