Answer:
<h2> P = 98 cm</h2>Step-by-step explanation:
Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.
Perimeter:
P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98

Answer:
y = - x -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 5) and (x₂, y₂ ) = (2, - 5) ← 2 points on the line
m = =
= -
, thus
y = - x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (2, - 5), then
- 5 = - + b ⇒ b = - 5 +
= -
y = - x -
← equation of line
