Well an octagon has 8 sides and if each side is 4 feet long then it is 8x4 so that equals 32.
Your answer is B) 32 Feet.
Answer:
slope=-1.1/500
y-intercept=212.0
Step-by-step explanation:
the y-intercept is always the number next to x, on the y side.
the boiling point is going down by 1.1
If you need to evaluate the answer is 1.2
Answer:
29.5 or 30 (rounded)
Step-by-step explanation:
Add 12 and 47 together and divide by 2 because there are 2 numbers.
81=16x²+24x+9
72=8(2x²+3x)
9=2x²+3x
0=2x²+3x-9
0=(2x-3)(x+3)
X=3/2 or -3
18=36x²+12x+1
0=36x²+12x-17
x=(-12±√(144-4(36)(-17))/2(36)
X=0.54 or 0.874
28=25x²+40x+16
0=25x²+40x-12
X=(-40±√(40²-4(25)(-12))/2(25)
X=-1.858 or 0.258
