Answer:
The porch is 17 ft by 17 ft
Step-by-step explanation:
The perimeter of a square is
P = 4s where s is the side length
P = 4( 3x+2)
P = 12x+8
We know P = 14x-2
14x-2 = 12x+8
Subtract 12x from each side
14x-2 -12x = 12x+8-12x
2x -2 = 8
Add 2 to each side
2x-2 +2 = 8+2
2x= 10
Divide by 2
2x/2 = 10/2
x = 5
The side is 3x+2
3*5+2
15+2
17

Answer:
(-2.4, 37.014)
Step-by-step explanation:
We are not told how to approach this problem.
One way would be to graph f(x) = x^5 − 10x^3 + 9x on [-3,3] and then to estimate the max and min of this function on this interval visually. A good graph done on a graphing calculator would be sufficient info for this estimation. My graph, on my TI83 calculator, shows that the relative minimum value of f(x) on this interval is between x=2 and x=3 and is approx. -37; the relative maximum value is between x= -3 and x = -2 and is approx. +37.
Thus, we choose Answer A as closest approx. values of the min and max points on [-3,3]. In Answer A, the max is at (-2.4, 37.014) and the min at (2.4, -37.014.
Optional: Another approach would be to use calculus: we'd differentiate f(x) = x^5 − 10x^3 + 9x, set the resulting derivative = to 0 and solve the resulting equation for x. There would be four x-values, which we'd call "critical values."
