Answer:
x>-9
Step-by-step explanation:
The given inequality is :
-3x - 7 < 20
We need to find the solution of the inequality using graph.
-3x - 7 < 20
Add 7 to both sides
-3x-7+7 < 20+7
-3x <27
x>-9
Hence, the attatched graph shows the solution of the given inequality.
Answer:
A(n) = L(n) × W(n) and
Step-by-step explanation:
We are given that the length of the rectangular garden is L and width is W.
Also, in terms of 'n',
Length is given by, L(n) = n + 2
Width is given by, W(n) = 0.5n + 1.
Now, we know that, Area of rectangle = Length × Width.
Therefore, area of Kirti's garden is given by, A(n) = L(n) × W(n).
Thus, formula of area in terms of L(n) and W(n) is A(n) = L(n) × W(n).
Moreover, as A(n) = L(n) × W(n).
i.e. A(n) = (n+2) × (0.5n+1)
i.e.
i.e.
i.e.
Hence, the formula for area in terms of 'n' is .
