The sides
12-3a
12-3a
4(2a-5)=8a-40
so for perimeter we + them
(12-3a)+(12-3a)+(8a-40)
=
2a-16
Are you doing FLVS? IF so I need hep
Well you would just multiply 374 by 15 and that would be your answer
If C= (-10, -9, -8, -7 ,-6 , -5) and D= ( -6, -5, -4, -3, -2, -1, ) , what is C n D ?

Answer:
C ∩ D = -5, -6
Step-by-step explanation:
Commons ones in both C and D are -5 and -6
If x is the age of S
And y is the age of K
So we have x=y+3
And the second equation is x-3 + 2/3)y = 12
We have to solve the system
x-y=3
x+2/3y=15
we find x=10.2 and y=7.2
