Answer:

DC=12\ units

Step-by-step explanation:

Step 1

<u>Find the value of y</u>

In this problem we know that

AD=DC -----> equation A

ED=DB

see the attached figure to better understand the problem

so

we have

AD=y+6

DC=2y

substitute the values in the equation A

y+6=2y

solve for y

2y-y=6

y=6\ units

Step 2

Find the value of DC

we have that

DC=2y

substitute the value of y

DC=2(6)=12\ units

Which expression is a linear factor of x6 +x-66?
Naddik [55]

Answer:

Option D.

Step-by-step explanation:

The given expression is

x^6+x-66

It is a polynomial.

(x-c) is a linear factor of polynomial p(x) if p(c)=0.

Substitute x=-1 in the given expression.

(1)^6+(1)-66=-64\neq 0

It means (x+1) is not a linear factor of given expression.

Substitute x=-2 in the given expression.

(-2)^6+(-2)-66=-4\neq 0

It means (x+2) is not a linear factor of given expression.

Substitute x=-4 in the given expression.

(-4)^6+(-4)-66=4026\neq 0

It means (x+4) is not a linear factor of given expression.

None of the given options are a linear factor of given expression.

Therefore, the correct option is D.

Lisa had 1750 stamps. Mark had 480 fewer stamps than Lisa. Lisa gave some stamps to Mark. Now Mark has three times as many stamp
FrozenT [24]
L: 1750, M:1750-480=1270
Lisa gave some stamps to Mark so Lisa now has 1750-x and Mark has 1270+x. Mark also has 3 times as many as Lisa now: (1750-x)*3=1270+x
5250-3*x=1270+x
4*x=3980, x=3980/4, x=995
So Lisa gave 995 stamps to Mark.
At first Mark had 1270 stamps. Lisa now has 1750-995=755 stamps.

What is the center and radius of the circle?<br> (x-2)2 +(y+3)2 = 49
ivolga24 [154]

Answer:

Center: 2, -3

Radius: 7

Step-by-step explanation:

The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.

The radius is equal to the square root of the constant on the other side.

The square root of 49 is 7.
