Answer:
5 spaces
2×(-5)=-10
Answer=10
Step-by-step explanation:
The correct answer is 2x^ 2 + 3x - 119 = 0.
We can find this by starting with naming one of our unknowns as x. We can choose either, but for ease, we'll use the width.
Width = x
Now since the length is equal to twice the width plus 3, we can express the length as follows.
Length = 2x + 3
Now we also know that the area is equal to 119 and that length times width equals area. So we can use that equation and what we know to find our actual equation.
Length*Width = Area
(2x + 3)(x) = 119
2x^2 + 3x = 119
2x^2 + 3x - 119 = 0

Step-by-step explanation:
Answer:
18 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2880°, thus
180° (n - 2) = 2880 ( divide both sides by 180 )
n - 2 = 16 ( add 2 to both sides )
n = 18
