Answer:
Regular Octagon
Step-by-step explanation:
There are only three regular shapes that tessellate – the square, the equilateral triangle, and the regular hexagon. All other regular shapes, like the regular pentagon and regular octagon, do not tessellate on their own.
Example: 
We can see that there is more than one number with the variable x, therefore, we say they're ''like terms'' and because of that they can be summed. We do this with all of the other numbers with similar variables. If no numbers with similar variables are left, like 4a, you don't do anything but write them as they are. You can also see that 8 and 9 can also be summed because neither of them has a variable, therefore they're similar.
In this step, you just do the operation with the numbers and keep the same variable.


since there are not more numbers similar in variables, this operation is done.

Answer:
degree
Step-by-step explanation:
The angle between the bottom of the ladder and the ground is given by

Where
B = distance between wall of house and the foot of ladder
L = Length of the ladder
Substituting the given values we get -

Answer:
107, there is two lines after that so 108 109 and the last line is 110 so your answer will be 107 degrees.
Step-by-step explanation:
Answer:
Ok y= 2x + b
b referring to any number less than -2 and more than -2
so y=2x+4 can work
Step-by-step explanation:
parallel lines in slope-intercept form have the same slope, i.e. the same 'm' value or coefficient of <em>x</em><em> </em> but different interceptions
