Answer:
Step-by-step explanation:
we have
5x+6y= -11
5x-2y=-3
we will multiply first equation with -1
-5x-6y=11 and add it with the second
5x-2y=-3
-8y=8
y=-1
we go to our original equation and replace y=-1
5x-6=-11
5x=-11+6
5x=-5
x=-1

Order from least to greatest
Comparing 16390, 16550 and 16237.
The order of arrangement from least to greatest is:
16327, 16390 and 16550.
So, we have:



Answer:
√20 units.
Step-by-step explanation:
Please see attached photo for diagram.
The other leg of the triangle is x as shown in the attached photo.
Using the pythagoras theory, we can obtain the the value of x as follow:
x² = 4² + 2²
x² = 16 + 4
x² = 20
Take the square root of both side.
x = √20 units
Therefore, the value of the other leg x of the triangle is √20 units
