Answer:

199 in.

Step-by-step explanation:

We already now what the bottom two sides lengths are but we need to find the length of the top 2 sides.

To find the side lengths we can use the area of the right triangle on the top with the area of 15 in. to do that we need to find the lengths of the two dotted red lines making the right triangle using process of elimination the lengths of the left side is 3 the bottom length is 10. the we use the Pythagorean theorem to find the length of the perimeter. 10^2+3^2=109 109/2= 54.5. the length of the top two sides are 54.5. To now find the perimeter we add the length of one of the top 54.5 and one of the bottom 45 to get 99.5 then multiply it by 2 99.5*2= 199 the perimeter of the window is 199 in.

What’s the equation for this
LekaFEV [45]
<h2>Answer:</h2>

Hope it work for u

<h2>Step-by-step explanation:</h2>

We can make points from the given figure as ,

1 point =(x1, y1)=(-2, -3)

2nd point =(x2, y2)=  (0, -6)

3rd point = (x3, y3)=(2 , -9)

Now the equation of line is,

<h2>Y=m X+ c  where   m is slope and c is constant </h2>

now two point formula of slope is ,

<h2>m = y2-y1/x2-x1</h2>

putting points in it we get

m=(-6-(-3))/(0-(-2)

m=-3/2 is slope

Now to find C putt the value of m and 3rd point in equation of line we get

y3=m(x3)+c

-9=(-3/2)(2)  +c

C= -9+3

C=-6  is value of c

Now at last putt the value of C and m in equation of line we get the required equation ,

<h2><u>Y=(-3/2)X-6  </u> Ans</h2>

E-4 - 5 - 6 - → The perimeter of a rectangle is 425 yards. The length and width of the rectangle are each multiplied by 6. What
Alex73 [517]

Answer:

2550yards

Step-by-step explanation:

Perimeter of a rectangle = 2L + 2W

L is the length

W is the width

If perimeter of a rectangle is 425 yards, then;

425 = 2L + 2W

425 = 2(L+W)

L+W = 425/2 .... 1

If the length and width of the rectangle are each multiplied by 6

P = 6(2L) + 2(2W)

P = 12L + 12W

P = 12(L+W) .... 2

Substitute 1 into 2

P = 12(425/2)

P = 6*425

P = 2550yd

Hence the perimeter of new triangle is 2550yards

lucas lives 5/8 mile from school.kenny lives twice as far as lucas from school.how many miles does kenny live from school
dexar [7]
<span><span>1.       </span>Lucas Lives 5/8 miles from their schools
=> 5/8 miles is equals to:
=> 5 / 8 = 0.625 miles.
Now, the problem says that Kenny lives twice as far as Lucas from their school.
Therefore, we only need to multiply the total number of miles of Lucas distance from house to school to be able to get what is the distance of Kenny’s house to school
=> 0.625 * 2 = 1.25 miles or 1 and ¼ miles.</span>
