Since BD is the perpendicular bisector of AC, then AB = BD, so:
6x = x+15
5x=15
x=3
CB = 3+15 = 18
Answer:
2.67 seconds
Step-by-step explanation:
Distance covered by the dog = 40 ft
The rate at which the dog runs (speed) = 15 ft/s
But,
speed = 
So that,
time = 
= 
= 2
time = 2.6667 s
It would take the dog 2.67 s to mess.
Answer:
B. 1 1/7
Step-by-step explanation:
-9 2/7-(-10 3/7)
=-9 2/7+10 3/7
=1 1/7
Therefore, B. 1 1/7

Answer: (3x−2)(4x−1)
Step-by-step explanation:
<em>Start factoring with -11x.</em>
12x^(2)-11x+2
12x2+(−8−3)x+2
12x2+(−8x−3x)+2
12x2−8x−3x+2
<em>Factor the highest common denominator of each group.</em>
<em>Group the first two terms and the last two.</em>
(12x2−8x)+(−3x+2)
<em>Factor the highest common denominator (MCD) of each group.</em>
<em>4x(3x−2)−(3x−2)</em>
<em>Factoring the highest common denominator 3x−2.</em>
(3x−2)(4x−1)
