<span>False.
-2(3x - 4) distributes to become -6x + 8
Thus, it is easy to tell it is false:
-2(3x - 4)= -6x - 8
-6x + 8 = -6x - 8
Add 6x to both sides;
8 </span>≠<span> -8</span>

Step-by-step explanation:
isosceles triangles are not always acute. An isosceles triangle has two of its sides and internal angles being equal.
Answer:
17
Step-by-step explanation:
First of all, based on the Pythagorean theorem, a^2 + b^2 = c^2
(it's very important that the ∠ABD angle is 90 degrees)
8^2 + 15^2 = s and 5^2 + 15^2 = CD (but the original question doesn't want the value of CD, so we just need to solve for s)
64 + 225 = 289 now remember, 289 is s^2, and we only want the value of s, so we have to find its square root: √289 = 17
