The first and last represent functions, no function has an input with two separate outputs

length is nine inches less than twice width. L = 2W - 9
perimeter is 84 inches 2L +2W = 84
Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing
2(2W-9) + 2W = 84
4W - 18 + 2W = 84
(4W+2W) = 84+18
6W = 102
W = 102/6 = 51/3
L = 2(51/3) - 9
= L= 17-9
L=6

Answer:
zero triangles. No triangle can be formed with angles measuring 70°, 70° and 70°
Explanation:
In any triangle (regardless its type), the sum of the interior angles should always be 180°.
Now, assume we have 3 angles each measuring 70°.
Sum of these three angles = 70 + 70 + 70 = 210° which is greater than 180.
Since we mentioned that the sum on interior angles MUST be 180, therefore, the given measurements cannot be combined to form a triangle.
Hope this helps :)
