The scale factor of the length of the sides of the cubes is 2:3
The ratio of group 1 to group 2 to total is 4:7:11.
4:7:11= x:y:33
11*3=33
Multiply the other numbers by 3 to get the answers for x and y.
x= 4*3=12
y= 7*3=21
Final answer: Group One-12, Group Two-21
L=3W+10 and P=2(L+W)=36
36=2(3W+10+W)
36=8W+20
8W=16
W=2 and since L=3W+10=16
W=2 and L=16
The discriminant of this equation is 49. The solutions for this equation are x=2 and x=-

I hope that helps.
Thats simple!
h(x)=

find h(-8)
All we need to do is PLUG IN THE -8
h(-8)=

=

(negative²=positive, negative×positive=negative)
=

h(-8)=
-8
