Answer:
Step-by-step explanation:
So this is an exponential equation because it is doubling each day.
So you will first determine the equation f (x)
The answer would be 7/4 because you would just divide both the 21 and 12 by 3
Answer:
658.91$
Step-by-step explanation:
Find the total cost
flight cost 397$
staying at the hotel for 6 night cost 6 x 28.43£
= 170.58£ = 233.69$
breakfast for 4 morning cost 4 x 5.15£= 20.6£
= 28.22$
Total cost is 397$+233.69$+28.22=658.91$
Answer:
The length of the garden=14 feet
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the garden</em>
length of the garden=x feet
width of the garden=(x-4) feet
<em>Step 2: Determine the area of the garden</em>
Area of the garden=length×width
where;
area=140
length=x
width=x-4
replacing'
x(x-4)=140
x²-4x-140=0, solve the quadratic equation;
x={-b±√(b²-4ac)}/2a
x={4±√4²-4×1×-140}/2×1
x={4±√(16+560)}/2
x={4±√576}/2
x=(4±24)/2
x=(4+24)/2=14, or (4-24)/2=-10, take x=14
The length=14 feet, width=(14-4)=10 feet
The length of the garden=14 feet
