Answer:
16.67
Step-by-step explanation:
Step 1: We make the assumption that 20 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=20.
Step 4: In the same vein.
Step 5: This gives us a pair of simple equations
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
Step 7: Taking the inverse (or reciprocal) of both sides yields
48 ÷ 24 = 2
24 goes into 48 2 times.
Solve for x.
Minus 6 from both sides. I will look like this: 5x+6-6=-4-6. It now equals 5x=-10. Divide both sides by by 5. Now, x=-2
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
