Answer:b
Step-by-step explanation:
(x-9)(x-3), because -9 and -3 make a sum of -12 and a product of +27
Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)
Answer:
Step-by-step explanation:
The volume is calculated like:
V= length* hauteur* wide
V= 5* 2 3/4* 10 1/2
