Answer:
Perimeter: ![4x^2-2x+8](https://tex.z-dn.net/?f=4x%5E2-2x%2B8)
Area: ![8x^2-4x](https://tex.z-dn.net/?f=8x%5E2-4x)
Step-by-step explanation:
I will assume the question asks for perimeter and area of the rectangle with given dimensions.
The height is "4"
The width (assuming) is "
"
First, the perimeter:
Perimeter is sum of all 4 sides of a rectangle, so we have 2 widths and 2 lengths, we sum them up:
![Perimeter=4+2x^2-x+4+2x^2-x=4x^2-2x+8](https://tex.z-dn.net/?f=Perimeter%3D4%2B2x%5E2-x%2B4%2B2x%5E2-x%3D4x%5E2-2x%2B8)
Now, the area:
Area is the height times width, so it will be:
![Area=4*(2x^2-x)=8x^2-4x](https://tex.z-dn.net/?f=Area%3D4%2A%282x%5E2-x%29%3D8x%5E2-4x)
Answer:
If it doubles every 7 years, then in 35 years it has doubled 5 times. Divide +
100,000 by 25
Step-by-step explanation:
.81 as a fraction is 81/100
It is 81/100 because you need to count the place of the number after the decimal, in this case it is the hundredths. 100 will be your denominator. Then you move the decimal over to the right 2 times and get .81------>>> 81.
81 is your numerator. Your answer is 81/100
Answer:
42
Step-by-step explanation:
b to the second power thats 1 plus 1 plus 5 times -1to the second power plus seven times 7 and 6 get you the answee 42
Answer:
30
Step-by-step explanation:
The area would have been 80*x=1600.
that means x=60. So, two pennant bases are 60.
That means one pennant base is 30.
