Answer:
B. BD = 9
Step-by-step explanation:
Simply set the 2 equations equal to each other (both are congruent due to perpendicular bisector):
6x + 3 = 3x = 6
3x + 3 = 6
3x = 3
x = 1
Then substitute 1 for <em>x</em> in BD
6(1) + 3
6 + 3
BD = 9
4-9= -5 that is the answer
Answer:
x = 4 or x = -1
Step-by-step explanation:
2x^2 - 8x + 6 =0
divide by 2 we get : x^2 -4x +3 = 0
(x -4) (x+1)
x = 4 or x = -1
Answer:
S ≈ 16.49 cm and R ≈ 16.76 cm
Step-by-step explanation:
We are given that:
Length = 16 cm
Width = 4 cm
Height = 3 cm
Thus,
The diagonal S of the bottom side is given by pythagoras theorem;
S² = 16² + 4²
S² = 256 + 16
S² = 272
S = √272
S ≈ 16.49 cm
Since we now have the bottom diagonal, then we can use Pythagoras Theorem to find the diagonal "R" of the box:
So, R² = S² + 3²
R² = (√272)² + 9
R² = 272 + 9
R = √281
R ≈ 16.76 cm
