What is the perimeter of a triangle whose sides are 4x, 3x+5, and 9-x?
1 answer:
Answer:
if these expression represent side lengths, then you simply add those three expressions, and that's the perimeter.
Step-by-step explanation:
I explore this idea a bit. obviously x < 5 (because 5-x has to be positive.
2x-5 > 0 is a requirement, also, so x > 2.5 is required.

The answer is 4.5 for the side length of the pentagon and 7.5 is the side length for the triangle because 7.5*3(3 sides) = 22.5 and 4.5*5(5 sides)= 22.5. The perimeter is 22.5

Answer:
Step-by-step explanation: 6z=-2-10
6z= -12
z=-12/6
then z= -2
4x/15 = 60/x 4x^2 = 900 x^2 = 225 x = 15
