Answer:
y= 1/2 is the answer.
Step-by-step explanation:
Given:
Area of polygon = 484 cm²
apothem 12.1 cm
sides of length = 10 cm
no. of sides = x
Area of a regular polygon = 1/2 perimeter * apothem
484 cm² = 1/2 * (10cm * x) * 12.1cm
484 cm² = 6.05cm * 10cm * x
484 cm² = 60.5 cm² * x
484 cm² ÷ 60.5 cm² = x
8 = x
The polygon is an OCTAGON. It has 8 sides.
Perimeter = 10 cm * 8 sides = 80 cm
484cm² = 1/2 * 80cm * 12.1 cm
484cm² = 1/2 * 968 cm²
484 cm² = 484 cm²
Answer:
factor:
x^2+2x+2x+4
x(x+2)+2(x+2)
(x+2)(x+2)
100x^2+20x+1
100x^2+10x+(10x+1)
10(10x+1)+(10x+1)
(10x+1)(10x+1)=(x+2)(x+2)
Hope this helps you
Answer:
<h2>-1 3/7 is larger</h2>
Step-by-step explanation:
To figure out which is larger, convert each of these mixed numbers to decimals.
-1 3/7 = -1.42857142857
-1 1/2 = -1.5
Negative numbers are larger the closer they are to 0. So, -1 is larger than -2, since -1 is closer to 0.
Since -1.5 < -1.43, -1 3/7 is larger than -1 1/2 since it is closer to 0.
