Step-by-step explanation:
First find the number of green balls in the basket:
= Total - yellow - blue - red
= 18 - 4 - 6 - 2

= 33.3%
Answer:
the answer would be A :) just took the test
Step-by-step explanation:
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35
minus original aera
which is 5 by 7 which is 35
4a²+24a+35-35=4a²+24a
3rd option I think, can't tell which is which
