Answer:
the second one 9v+36
Step-by-step explanation:
because with the way it set up it wants you to multiply 9 by everything inside of the parenthesis so 9 times v is 9v and 9 times 4 is 36 thus 9v+36 and you also take the addition symbol from inside the parenthesis.
Expand,
=
So the third choice would be your answer!
Hope this helps!
Answer:
4x − 10
Step-by-step explanation:
The width of rectangle A is 2x+4 and the length of rectangle A is x-1. This makes the perimeter
2(2x+4)+2(x-1)
= 4x+8+2x-2
= 6x+6
The width of rectangle B is 3x+1 and the width of rectangle B is 2x-3. This makes the perimeter
2(3x+1)+2(2x-3)
= 6x+2+4x-6
= 10x-4
Subtracting Perimeter B - Perimeter A, we ahve
(10x-4)-(6x+6)
= 10x-4-6x-6
= 4x-10
