Answer:
Let l be length and w be the width
l = 2w+12
Area = (2w+12)*w = 224
2w^2 + 12w - 224 = 0
w^2 + 6w - 112 = 0
using quadratic formula
w=[ -6 +- {36- 4*1*(-112)}^0.5]/2*1
w = [-6 +- {484}^0.5]/2
w = [-6 +- {22}]/2
w = 16/2 or -28/2
w = either 8 or -14
Width can not be a negative number
wI’d think= 8 ft
length = 2*8+12 = 28 ft
Step-by-step explanation:
Answer
-8/3 (fraction)
or in decimal form it would be -2.6 (the six would be repeating)
Step-by-step explanation:
let the number = x
x*80/100 = 55
x = 5500/80
x=68.75
After rounding off, it will remain 68.75
Answer:
y=2x-4
Step-by-step explanation:
If you are asking for point slope form, that would be it
