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

1.5
Step-by-step explanation:
Attached to this answer is the diagram of the box plot described in the question, and the means from the plot are calculated thus;
Students; no. of siblings
student 0 2
student 1 4
student 2 7
student 3 5
student 4 2
Total 20
Mean no. of siblings = (total number of siblings) ÷ (total number of students)
Note that number of students here are the once that had at least one sibling, others without siblings are not used in the calculation, hence 5 students (student-0 to student-4) make up total number of students, while the remaining 4 students (student-4 to student-9) are disregarded.
Therefore, mean = 20 ÷ 5 = 4 siblings.
