Hello!

You first have to find the width

We can find this use the Pythagorean theorem

12^2 + b^2 = 15^2

Square the numbers

144 + b^2 = 225

Subtract 144 from both sides

b^2 = 81

Take the square root of both sides

b = 9

The width is 9

To find the perimeter you do 2l + 2w

Put in the values 2(12) + 2(9)

24 + 18 = 42

The perimeter is 42cm

To find the area you multiply the sides

12 * 9 = 108

The area is 108cm^2

The answer is D

Hope this helps!

Write an equation for the line that connects A (-4,8) and B (6,3)

Mazyrski [523]

Answer:

7y+5x=76

Step-by-step explan

A (-4,8) and B (6,3)

First find the slope;

m= (y2-y1)/(x2-x1)

m=(3-8)/(3+4)

m=-5/7

now using equation of line

y-y1= m(x-x1)

y-8=-5/7 (x+4)

y-8=(-5x+20)/7

7(y-8)= -5x+20

7y-56=-5x+20

7y+5x=20+56

7y+5x=76
