Step-by-step explanation:
-3(x - 4) + x(2x + 3)
= (-3x + 12) + (2x² + 3x)
= 2x² + 12
= 2(x² + 6).

Using the distance formula Then we assign the points letter for simplicity
. The distance formula gives us the magnitude between two points hence,
Answer:
C
Step-by-step explanation:
The triangle inequality theorem tells us that if two sides of a triangle are known (let it be side a and b), we can know the length of range of third side (side c). By:
a-b< c < a+b
So sides are given 29 and 40.
Sum is 29 + 40 = 69
Difference is 40 - 29 = 11
Hence, the third side would be BETWEEN 11 and 69
C is the correct choice.
