The perimeter of quadrilateral JKLM is 90 centimeters. Which is the length of side KL?

Mathematics

The perimeter of an object is given by the sum of all the sides of the object. Thus the perimeter of a quadrilateral is the sum of the four sides of the quadrilateral.

Given a quadrilateral with sides: n, 2n - 12, 3n + 4, n + 7

The sum is n + 2n - 12 + 3n + 4 + n + 7 = 7n - 1 = 90

Thus, 7n = 90 + 1 = 91 and n = 91 / 7 = 13.

Therefore, the length of the side KL is n = 13 centimeters.

write the equation in slope intercept form for the line that passes through (-2,2) and is parallel to 2x+4y=16
ratelena [41]

Answer:

<h3>Step 1 - Find the gradient of 2x + 4y = 16</h3>

2x + 4y = 16

4y = 16 - 2x

y = 4 - 1/2x

gradient = -1/2

<h3>Step 2 - Find the Equation</h3>

y - y1 = m(x - x1)

m = gradient, (x1, y1) = (-2,2)

y - 2 = -1/2 (x + 2)

y - 2 = -1/2x - 1

y = -1/2x + 1 → ANSWER

Hope it helps!
