Answer:
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
Answer:
no it is not possible
Step-by-step explanation:
By factor theorem, f(-4)=7,therefore x+4 is not a factor of f..and remainder when decided by x+4 is 7
