two sides of an isosceles triangle with a perimeter of 270 cm are in a ratio of 4:7. Find the possible measure(s) of the base

Base  = 126 cm or 60 cm

Step-by-step explanation:

Ratio of sides of isosceles triangle = 4 : 7

Sides  are = 4x , 7x

If smallest sides of the isosceles triangle are equal, then

three sides are = 4x , 4x , 7x

Perimeter = 270 cm

4x + 4x + 7x = 270

           15x = 270

              x = 270/15

              x = 18

Base = 7x = 7*18 = 126 cm

If largest sides of the isosceles triangle are equal, then

Three sides are = 7x , 7x , 4x

7x + 7x +4x = 270

           18x = 270

              x =  270/18

              x = 15

Base = 4x = 4 * 15 = 60 cm

i believe the answer is the polygon, heptagon.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
