Solution:
The perimeter of rectangle is given as:
P = 2(length + width)
From given,
length = ?
width = 55 feet
perimeter = 290 feet
Therefore,
290 = 2(length + 55)
[tex]length + 55 = \frac{290}{2}\\\\length + 55 = 145\\\\length = 145 - 55\\\\length = 90[/tex]
Thus length of rectangular lot is 90 feet
Solution:
Given equation is:
[tex]y = (x + 1)^2 - 10[/tex]
To find: y when x = -2
Substitute x = -2
[tex]y = (-2 + 1)^2 -10\\\\y = -1^2 -10\\\\y = 1 - 10\\\\y = -9[/tex]
Thus y is -9 when x is -2
