Answer:

4x+12y = 4 (x+3y)

35x+50y = 5 (7x+10y)

18x+9y = 9 (2x+y)

32x+8y = 8 (4x+y)

100x+700y = 100 (x+7y)

Step-by-step explanation:

You basically have to figure out what x and y are being divided by to get the x and y on the other side and put that before the parenthesis. For example in the first question in order to get x you must divide 4x by 4 and to get 3y you must divide 12y by 4 as well.

Write an equation of the circle with center (6, 2) and radius 4.

luda_lava [24]

Answer:

$(x-6)^2+(y-2)^2=16$ .

Step-by-step explanation:

$(x-h)^2+(y-k)^2=r^2$ is the equation for a circle with center (h,k) and radius r.

You are given center (6,2) and radius 4.

So we will replace h with 6 and k with 2 and r with 4.

This gives us:

$(x-6)^2+(y-2)^2=4^2$

Simplify:

$(x-6)^2+(y-2)^2=16$ .

In the triangle ABC if angle A is 20 degrees, angle B is 35 degrees and the side between (side C) them is 100, what is the appro

docker41 [41]

Answer:length of side a is 42

Step-by-step explanation:

The given triangle ABC is shown in the attached photo. The length of side BC is a. The length of side AC is b and the length of side AB is c = 100

The sum of the angles in a triangle is 180 degrees. Therefore.

Angle A + angle B + angle C = 180. Therefore,

20 + 35 + angle C = 180

55 + angle C = 180

Angle C = 180 - 55 = 125 degrees. To determine the length if a, we would apply the sine rule which is expressed as

a/SinA = b/SinB = c/SinC

Therefore,

a/Sin20 = 100/Sin125

aSin125 = 100sin20

a × 0.8192 = 0.342 × 100

0.8192a = 34.2

a = 34.2/0.8192

a = 41.75

Approximately 42
