What amount of area remains dry? Show your work to explain how you go
your answer, to the nearest square meter. (Dry area is in the shaded
region.)

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: the is put the 450

step-by-step explanation:

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
