Answer:

-3, -1 and 1

Step-by-step explanation:

Assuming n is the first of the three integers, you can express this as the equation:

6(n + n+2 + n+4) = -18

which simplifies to

18n = -54

n = -3

Geometry circles question

CaHeK987 [17]

Answer: 14

----------------------------------------------

Explanation:

Using the intersecting chord theorem, we can say,

AP*PB = CP*PD
(x+2)*6 = 7*x
6x+12 = 7x
6x+12-6x = 7x-6x
12 = x
x = 12

If x = 12, then,
AP = x+2
AP = 12+2
AP = 14

Elena is feeding her neighbor's dogs each dog gets two thirds cup of dog food and she uses three and one third cups of food how

MrRa [10]

Answer:

Total number of dogs is 5.

Step-by-step explanation:

Cups of food each dog gets= $\frac{2}{3}$

Here,each dog eats two-third cups of dog food.

Amount of dog food used= $\frac{10}{3}$

A total of three and one-third cups of food is used up.

Let the number of dogs be x.

To find the number of dogs,divide total dog food used by the amount of dog food eaten by each dog.

Hence, x = $\frac{\frac{10}{3} }{\frac{2}{3} }$

x = $\frac{10}{2}$

x =5

Show that sin (x + pi) = -sin x.

Lunna [17]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

$sin(A + B) = sin A cos B + cos A sin B$

In this problem we have

$sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)$

Remember that

$sin(\pi) = 0$

$cos(\pi) = -1$

substitute

$sin(x + \pi) = sin(x)(-1) + cos(x)(0)$

$sin(x + \pi) = -sin(x)$

WILL GIVE BRAINLIST i cant remember how this one goes at all

SOVA2 [1]

Answer:

B' = (-2,2)

Step-by-step explanation:

So to solve this you need to find the current coordinates of B.

B = (-5,4)

So it says the translation is (x+3, y-2)

Let us substitute in the values

(-5 + 3, 4 - 2)

So the new coordinate is

(-2,2)
