THEN SIMPLIFY
-8r^13
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
<h3>
</h3>
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-7, 1), and (-4, -3)
The slope is
<h3>
</h3>
We have the final answer as
<h3>
</h3>

Answer:
The window is 8 meters high.
Step-by-step explanation:
You multiply .2 by every number in the parentheses. So .2 times 2.50, which is 0.5, .2 times 4.95, which is .99 and .2 times by 6, which is 1.2. then you add .5, .99 and 1.2 to get 2.69.
So firstly you are given the external angles, to find the internal angles, you do 180-133=47
180-142=38
the internal angles in a triangle add up to 180, therefore it is
47+38=85
180-85=95
because you have to find the external angle=n you then need to take 95 away from 180
180-95=85
so the answer is A
