I believe the answer would be x20. Between the two parentheses there's a multiplication symbol. So you would just pretend that the parentheses aren't there cause the variable(s) (x) is/are like terms. So you would just multiply 10 times 2 and put out the x back in front of it
Let
width,w
length, l = 1.6w ...eqn 1
area, a = l × w ...eqn 2
subst for l in eqn 2
a = 1.6 w × w = 4000
4000 = 1.6 w^2
w^2 = 2500
w = 50
subst for w in eqn 1
l = 50 x 1.6 = 80
length = 80 yds
width = 50 yds

The answer is in my photos.
Answer: 3.5 gallons
Step-by-step explanation:
From the question, we are told that Chanasia has 8.75 gallons of paint and that she wants to use 2/5 of the paint to paint her living room.
The gallons of paint that Chanasia will use be gotten by multiplying 2/5 by 8.75 gallons. This will be:
= 2/5 × 8.75 gallons
= 0.4 × 8.75 gallons
= 3.5 gallons.
This means that Chanasia will use 3.5 gallons to paint her living room
