Answer:
The side length of a square is the square root of its area. We know that:
x2 + 4x + 4 = (x + 2)2
Therefore, the side length of the square is x + 2
Answer:
Step-by-step explanation:
How many times must you step back 8 inches after stepping forward 60 inches to end 28 inches from your starting point?
) Using formula for cicumference.
Circumference = Pi * diameter
Circumference = Pi * 80m
Circumference = 251.2m.
Total inside length of the curved ends.
2)Total distance round inside of track =
2(125) + 251.2m
= 250 + 251.2
= 501.2m
3) Area of circular ends =
Pi*r^2
= Pi*40^2
= 5024m^2
Area of central area (rectangle)
length * width
125m * 80m
= 10,000m^2
Total area inside track =
5,024m^2 + 10,000m^2
= 15,024m^2
Hope this helps.

Answer:
Rs. 42500
Step-by-step explanation:
100% + 25% = 125% ÷100 = 1.25
34000 x 1.25 = 42500
About 57 red pens were sold
<h3>Ratios and proportion</h3>
According to the information given:
number of packs of black pens sold: number of packs of red pens sold: number of packs of green pens sold = 7:3:4
- Total ratio = 7 + 3 + 4 = 14
- Total pen sold = 268
Number of red pens sold = 3/14 * 268
Number of red pens sold = 57 pens
Hence about 57 red pens were sold
