An equilateral triangle can be an isosceles triangle IF one of the sides has a different length than the rest and the angle measurement is different.

Step-by-step explanation:

I hope it helps

IT CAN BE

Step-by-step explanation:

BECAUSE ISOSCELES TRIANGLE IS A TRIANGLE WITH 2 SIDES EQUAL

EQUILATERAL TRIANGLE HAS ALL SIDES AND ANGLES EQUAL, so equilateral triangle also has 2 sides equal

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
