Answer:

6

Step-by-step explanation:

Any circle in the form

$(x+\alpha)^2 + (y+\beta)^2 = r^2$

Where r^2 is the radius squared, so

$r^2=36$

$r=6$

which of the following is a true statement a) if AB=CD,then 3CD=3(CD+1). b)if AB=CD,then AB-CD=A-C+B-D. c)if AB=CD,thenAB+EF=CD+

Free_Kalibri [48]

a) if AB = CD, then 3CD = 3(CD + 1) NOT TRUE

example: AB = CD = 1, then 3CD = (3)(1)=3 and 3(CD + 1) = 3(1 + 1) = 3(2) = 6

b) if AB = CD, then AB - CD = A - C + B - D NOT TRUE (it does not make sense because A, B, C and D are points)

c) if AB = CD, then AB + EF = CD + EF TRUE

because

AB = CD |add EF to both sides

AB + EF = CD + EF

d) if AB = CD, then 2AB = 2A + 2B NOT TRUE (it does not make sense because A and B are points).

Dont answer this PLEAS

Answer:

why? also the answer is 1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R

We add all the numbers together, and all the variables

1.6y+y-4/15y+7/6y-7=0

We add all the numbers together, and all the variables

2.6y-4/15y+7/6y-7=0

We calculate fractions

2.6y+(-24y)/90y^2+105y/90y^2-7=0

We multiply all the terms by the denominator

(2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

(+2.6y)*90y^2+(-24y)+105y-7*90y^2=0

We add all the numbers together, and all the variables

105y+(+2.6y)*90y^2+(-24y)-7*90y^2=0

Wy multiply elements

-630y^2+105y+(+2.6y)*90y^2+(-24y)=0

We get rid of parentheses

-630y^2+105y+(+2.6y)*90y^2-24y=0

We add all the numbers together, and all the variables

-630y^2+81y+(+2.6y)*90y^2=0

Well to be honest, you need to straight forward to her and tell her that you do not appreciate her copying you and tell her you dont want to be rude or anything, but this needs to stop.
