Answer:
<em>The value of the expression is 11</em>
Step-by-step explanation:
<u>Evaluate Expressions</u>
An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.
To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.
Let's consider the expression:

for x=10, y=-1, z=0
Substituting the variables for their values:



The value of the expression is 11
<span>An obtuse triangle will have one and only one obtuse angle. </span>
<span>The other two angles are acute angles.</span>
<span>The sum of the two angles other than the obtuse angle is less than 90º.<span /></span>
<span><span>The side opposite to the obtuse angle is the longest side of the triangle.</span></span>
<span><span>
</span><span>The points of concurrency, the Circumcenter and the Orthocenter lie outside of an obtuse triangle, while Centroid and Incenter lie inside the triangle.

The answer goes up by 12 each time
y = mx , where m is a slope,
m= rise/run
We have y = 15x, so m =15 and rise/run =15, then
rise = 15, run = 1
10x4=40. i dunno thats what i got from google lolll..
