Answer:
The length of the side of the original garden is 5 m.
Step-by-step explanation:
Let the original side of the garden be x.
SInce we are given that the side is incresed by 7 m.
So, the new side = x+7
Formula of area of square =
Where x is the side length of square .
So, area of garden after increasing the length of side by 7 =
Since we are given that the new total area of the garden will be
⇒
⇒
⇒
⇒
⇒
Thus the length of the side of the original garden is 5 m.
Answer:
D. 99
Step-by-step explanation:
You have to add the previous numbers with the recent number for example we started with 1 and 7 so you add that and get 8 then you add 8 with 7 and get 15, then you add 8 with 15 and get 23 and so on and so forth. this probably doesn't make sense but i'm %100 sure its 99
2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2
2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5
solution is : (-5,2)
