That's true.  The definition of an isosceles triangle is that it has at least 2 sides equal in length.  Therefore, isosceles can be equilateral, but equilateral cannot be isosceles.

How to find the slope from two points (14, -69) and (17, -57)
vampirchik [111]

Answer:

4

Step-by-step explanation:

to find the slope from 2 points, you do y2-y1/x2-x1

in this case, it would be -57-(-69)=12

and then x2-x1 is 17-14=3

so, the slope is 12/3 or 4

Solve the equation, and check the solutions 2(√x+3)=6.
zhannawk [14.2K]

Answer:

x = 0

Step-by-step explanation:

2(\sqrt{x}+3)=6

Expanding the left hand side we get

\Rightarrow 2\sqrt{x}+6=6

Taking 6 from left hand side to right hand side

\Rightarrow 2\sqrt{x}=6-6\\\Rightarrow 2\sqrt{x}=0

Dividing both sides by 2

\Rightarrow \sqrt{x}=\frac{0}{2}\\\Rightarrow \sqrt{x}=0\\\Rightarrow x=0

So, x = 0

Mkey [24]

Answer:

6π units

Step-by-step explanation:

Given::

Radius = 4

Angle measure of partial circle (θ) = 360° - right angle = 360° - 90° = 270°

Arc length = θ/360 × 2πr

Plug in the values

= 270/360 × 2 × π × 4

= 0.75 × 8 × π

= 6π units
