Answer:
Step-by-step explanation:
(b/45) +7 > 5
(b/45) > -2
b > -90
Perimeter is 17 m ≥ 2* length 4.7 +2*widths
b. 9.4+2w ≤ 17
a. (2/7)n -10.6 < 12.4
(2/7)n < 12.4 +10.6
(2/7)n < 23
2n < 23*7
n < 161/2
n < 80.5
Let the original side length be x. Then (x+2)^(in)^2 = 121 sq in.
Thus, x^2 + 4x + 4 = 121;
x^2 + 4x - 117 = 0 = (x-13)(x+9) = 0. Then x = 13 and x = -9.
We need to discard the negative result (-9).
The side of the original square is 9 inches. (answer)
Check: does (9+2)^2 = 121? Does 11^2 = 121? YES.
Answer:
4x+5y= -12
subtract 4x from both sides
5y = -4x - 12
divide by 5
y = -4/5 x - 12/5
-2x+3y= -18
subtract -2x
3y= -2x - 18
divide by 3
y= -2/3x -6
