Answer:

I. L = 17 cm.

II. W = 11 cm.

Step-by-step explanation:

Let the length of the rectangle be L.

Let the width of the rectangle be W.

Given the following data;

Perimeter of rectangle = 56cm

Translating the word problem into an algebraic expression, we have;

L = W + 6 .....equation 1

The perimeter of a rectangle is given by the formula;

P = 2(L + W)

56 = 2(L + W) ......equation 2

Substituting eqn 1 into eqn 2, we have;

56 = 2(W + 6 + W)

56 = 2(6 + 2W)

Opening the bracket, we have;

56 = 12 + 4W

4W = 56 - 12

4W = 44

W = 44/4

W = 11 cm

Next, we would find the length of the rectangle;

From eqn 1;

L = W + 6

L = 11 + 6

L = 17 cm

Draw scalene triangle ABC and extend side BC to the right of vertex C.
Doss [256]
Mark Brainliest please


See the image for the drawing
Let’s say the side BC is extended till D

1) measure of angle ACD = 105° ( angle ACD is exterior angle)
45 + 60 = 105
2) I found the answer by adding the values of Angle A and Angle B or by using the exterior angle property.
3) I observed that exterior angle property can be used here. Exterior angle property is that an exterior angle of a triangle is equal to the sum of the opposite interior angles.

Write an equation of the line in slope-intercept form.
kotegsom [21]

Answer:

y = - 2x

Step-by-step explanation:

(-3 , 6) (0 , 0)

m (slope) = (y - y') / (x - x') = (0 - 6) / (0 - (-3)) = -6 / 3 = - 2

y = mx + b b: y intercept

b = y - mx     (for poit (0,0))

b = 0 - 0 = 0

equation: y = - 2x
