Answer:

Democrats are 44

Independent there is 1

Step-by-step explanation:

55 Republicans
44 Democrats
1 Independent

Since you know there are 5 republicans for every 4 democrats you can divide 55/5 and get 11. Then you would multiply 11 by 4 for the number of Democrats. Then you would add 55+44=99. So there would be 1 independent.

Answer:

b = 17.55

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + b^2 = 18^2

b^2 = 308

square root them

b = 17.55

let me know if it is correct!

Step-by-step explanation:

Write and simplify an expression to represent the perimeter of a rectangle whose length is twice the width.

Answers

Answer: 2x+4x

Step-by-step explanation:

Let's say x is the width, or the short side and 2x is the long side or length (since the long side is twice as long as the short side).

let's add those together.

x+2x

But with a perimeter, you have two short sides and two long sides. so let's multiply this expression by two.

2(x+2x)

multiply the two by each number.

2x+4x
