Answer:4/1 (I think)
Step-by-step explanation:
It’s rise over run, so if you look at it what’s the rise what’s the run, of the middle point
Answer:
first one
Step-by-step explanation:
same x value can't have more than one y value
Answer:
Infinitely many.
Step-by-step explanation:
Combine like terms as shown below
x + <em>12</em> + 2x = <em>20</em> + 3x - <em>8</em>
Side one
x + 2x = 3x
Side two
<em>20 - 8 = 12</em>
Set the equation up again
3x + <em>12 </em>= 3x + <em>12 </em>
The equation is the same on both sides which means that the equation cancels itself out.
3x - 3x = 0 and 12 - 12 = 0
0 = 0 so there is infinitely many solutions because both sides equal the same thing.
Answer:
1,080 sq ft
Step-by-step explanation:
shape can be broken into a 25 ft x 25 ft square and a 35 ft x 13 ft rectangle
(you get 35 by taking the difference of 60 and 25)
25 x 25 = 625
35 x 13 = 455
total = 1,080
The sum of interior and exterior angle is 180, thus<span>Interior angle =180−72=108 degrees </span>Let n be the number of sides of the polygon<span><span>(n−2)×180 / n = interior angle =108</span></span><span>72n = 360</span><span> n = 5 sides, hence this is a pentagon.
Sum of the interior angles = 108*5 = 540 degrees.</span>
