Answer:
23
Step-by-step explanation:
The sides of a square are all the same length, so if 3 of them total 48, one of them must be 48/3 = 16.
If the length of the rectangle is 7 longer than the side of the square, it is
... 16 + 7 = 23
Answer:
y + 9 = -0.4(x-7)
Step-by-step explanation:
in slope form , we will use y - y1 =m ( x - x1) ,
which will be y + 9 = -2/5(x-7) ,
in reduced form , we have y + 9 = -0.4(x-7)
Answer:

Step-by-step explanation:
For the equation
use the substitution
Then the equation will take look

Solve this quadratic equation:

Thus,

5(n + 27) >= 6(n + 26)
5n + 135 >= 6n + 156
-n >= 21
n <= -21
