For letter d, i'm having a hard time trying to figure out how to find the area for that figure, !

Hi... Try spliting the square into 8 equal parts... 

I worked out the answer and the area for the figure d is

= (6a^2/8)(2 - pi) + a^2/2
where a is length of the side of the square.

Reach out to me if you had any difficulties

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

29933333.33

step-by-step explanation:

6×10=604000000÷60=66666.6666766666.6667×449=29933333.33
