No, because an equilateral triangle can only be an equilateral triangle if ALL three sides are equal, or congruent, in length. If only two sides are equal in length, then it is an isosceles triangle.
Answer:
Option a:
Step-by-step explanation:
1. By definition ![\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D)
can be written as 
.
2. Then, keeping this on mind, you have that ![\sqrt[4]{f}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bf%7D)
can be also written as following:
![\sqrt[4]{f}=f^{\frac{1}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bf%7D%3Df%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D)
3. Therefore, the rational exponent expression of is the option a:
Answer:
x=2
Step-by-step explanation:
Solve for x:
-20 = -10 x
-20 = -10 x is equivalent to -10 x = -20:
-10 x = -20
Divide both sides of -10 x = -20 by -10:
(-10 x)/(-10) = (-20)/(-10)
(-10)/(-10) = 1:
x = (-20)/(-10)
The gcd of -20 and -10 is -10, so (-20)/(-10) = (-10×2)/(-10×1) = (-10)/(-10)×2 = 2:
Answer: x = 2
