<span>Let the extension of the length and width be x.
The new dimensions are: Length = 8+x
Width =3+x
Area = 104 ft squared
Area of a rectangle = Length x Width
Therefore,
(8+x)(3+x) = 104
x^2 +11x +24=104
x^2 +11x +24-104=0
x^2 +11x-80=0
Factorize using splitting the middle term method.
X^2 +16x-5x-80=0
x(x+16)-5(x+16)=0
(x-5)(x+16)=0
either x-5 = 0 or x+16=0
x=5 or x=-16
length and width measure cannot be negative.
Therefore, the extension of the length and width is 5 feet each.</span>
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.

Answer:
The prepaid phone plan will have a steeper line and lower y-intercept.
I hope this is right
Step-by-step explanation:
prepaid phone plan y = .20x
contracted phone plan y = .02x + 50
Answer:
We have the measures:
1023 cm
2.3 m
8.72m
6430 mm
1200 mm
6.4 cm
2.5m
0.06km
Now let's write all those measures in the same unit, let's use meters.
We know that:
1cm = 0.01m
1mm = 0.001m
1 km = 1000m
Then, we can rewrie the measures as:
1023 cm = 1023*0.01 m = 10.23 m
2.3 m
8.72m
6430 mm = 6430*0.001 m = 6.430 m
1200mm = 1200*0.001 m = 1.2 m
6.4 cm = 6.4*0.01m = 0.064 m
2.5m
0.06km = 0.06*1000km = 60m
Then the order, from smallest to largest is:
6.4 cm
1200mm
2.3 m
2.5m
6430 mm
8.72m
1023 cm
0.06km
Since A=l*w*h,
A=4.5*7.25*6.5
A=212.0625
A=212.0 feet squared is the answer.
