Number of combinations = (6x5) ÷ 2 = 15
Answer:There are 15 combinations
To answer your question, it is shown in the graph below.
y=-3x-6 is parallel to y=-3x-2
Now all you have to do is divide -3x by -2 and 18 by -2 which would be:
Y= 3/2x-9
Answer:
Perimeter = 10 cm
Area = 6.25 cm²
Step-by-step explanation:







So to find the Perimeter of the square, we'll use this formula :





Hence, the perimeter would be 10 cm .


We know that the formula of Area to find the square is,

Note : The answer would always be in cm².





Hence, the area of the square would be 6.25 cm².
<em>We are done !</em>

Answer:
<em>x = 5</em>
Step-by-step explanation:
The figure shows two pairs of opposite sides parallel, so quadrilateral KLMN is a parallelogram. Angles N and L are opposite angles in a parallelogram, so their measures are equal.
m<N = m<L
5x = x + 20
4x = 20
x = 5
