Answer: 75
Step-by-step explanation:
To find the value of 6c-15, we first want to finc the value of c. Once we find c, we can plug it in and solve.
-5c+6=-69 [subtract both sides by 6]
-5c=-75 [divide both sides by -5]
c=15
Now that we have the value of c, we can plug it in and solve.
6(15)-15 [multiply]
90-15 [subtract]
75
The value is 75.

Answer:
Irrational
Step-by-step explanation:
it can not be written as a simple fraction
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent
Answer:
yes, they do
Step-by-step explanation:
added together it equals 254, so unless there is tax they have enough
