1a= (2x+5)+3x+15
1b= (2(4)+5)+3(4)+15=40
2a= (3x+5)•(4x-3)
2b= (3(2)+5)•(4(2)-3)=55
2c= 2(x) or 2(2)
How I got 2c is the perimeter of the rectangle LMNP subtract from (2(2)+9)+(2(2)+9)=26 which in return means you subtract 30 from 26 and get 4 which is 2(2) or 2x
N={1,2,3,4,5,6,....}
ElF={5,15,25,35,45,55,65,75....}
so let natural numbers to be n, so
a)count the distance between the numbers
b)add or subtract extra values
10n-5 would be one to-one correspondence.
Step-by-step explanation:
10 chices are possible Anne with Melissa
or Anne with Jennifer
or Anne with Karen
or Anne with Lisa
or Anne with Susan
also jean with melissa
or Jean with Jennifer
or Jean with Karen
or Jean with Lisa
or with susan
850 would be the answer. You would find this by multiplying it.
