Answer:
percentage decrease is always calculated like this
((orignal - new ) / original ) 100
So in this case
100-45= 55
55/100 is 11/20
11/20 * 100/1 is well simplified is 55
so 55%
-5(x+3)=-4x-15
-5x-15=-4x-15
-5x+4x=-15+15
-1x=0 /-1
x = 0

Answer:
11v^2 - 8v + 1
Step-by-step explanation:
(4v^2 - 5v - 1) + (7v^2 - 3v + 2)
open brackets
4v^2 - 5v - 1 + 7v^2 - 3v + 2
place like terms together (remember signs remain same )
4v^2 + 7v^2 - 5v - 3v + 2 - 1
add or subtract like terms
11v^2 - 8v + 1
