The 1st figure is correct, the 4th one seems very similar to the 1st one. But the red shape is closer to line k. So the 1st one is correct

Which of the following is the Perpendicular Bisector Theorem?

Korvikt [17]

The answer is B. On the off chance that a point is on the opposite bisector of a portion, at that point, it is equidistant from the endpoints of the fragment. Opposite of the Perpendicular Bisector Theorem: If a point is equidistant from the endpoints of the fragment, at that point it is on the opposite bisector of the portion.

The sum of 3y and 5 is 47

Musya8 [376]

3y + 5 = 47

Subtract the 5 so you have 3y on the left side and move it to the other side.

Now it’s:

3y = 47-5

3y = 42

Now, divide 3y by 3, so we get y by itself. Do the same thing to the other side.

y = 14

The length of a rectangular garden is three times its width, w. The area of the garden is 300 m². Explain why the expression 3w

kogti [31]

If the length is three times the width and the area of the rectangle is

300 $m^{2}$ then the length of rectangle is 30m and width be 10m.

Given that the length is three times the width and the area of the rectangle is 300 $m^{2}$ .

We are required to find the length and breadth of the rectangle.

Area of the rectangle is basically the product of length and breadth.

let the breadth of rectangle be w.

The length of rectangle will be 3w.

Area=Length*Breadth

300=3w*w

300=3 $w^{2}$

100= $w^{2}$

w=+10,-10 but ignore -10 because width cannot be negative.

Length=3w=3*10=30m

Width=w=10m

The area can be written as 3 $w^{2}$ because the area of rectangle is product of length and breadth.

Hence if the length is three times the width and the area of the rectangle is 300 $m^{2}$ then the length of rectangle is 30m and width be 10m.
