x² = 4
x = √4 or x = - √4
= +2 = -2
Answer:
no
Step-by-step explanation:
because triangle abc and triangle acer have unequal ratio of side lengths
Smallest #: x
Medium #: x + 2
Largest #: x + 4
Equation:
(x) + (x+2) + (x+4)= 108
3x + 6 = 108
3x = 102
x = 34
Largest #: x + 4
Largest #: 34 + 4
Largest #: 38
Answer:
