Answer:
Not a polygon
Step-by-step explanation:
[(3x+12)•(4x+4)]-(3x+8)-(4x)
[12x² + 12x + 48x + 48] - 3x - 8 - 4x
12x² + 60x + 48 - 7x - 8
12x² + 53x + 40
This is a degree 2 (quadratic) polynomial, not a polygon.
A polygon is an n-sided figure.
Example: A rectangle --> A four-sided polygon
Answer:
10 friends got into the fair
Step-by-step explanation:
If county fair cost is $2.5 per person
$10 to catch a trolley
total cost = $35
Total county fair cost= total cost - trolley cost
= $35 - $10
= $25
So if $25 was spent on county fair, then the number of friends that went is
$25/$2.5 = 10
That is total cost divided by cost per person gives number of persons
If this is a rectangle, then the answer is the length=96 unitsI just formed two linear equations that follow the information.
1. 2l + 2w= 256
2. l=3w
Then, I solved for w by using substitution. w is 32. I then multiplied it by 3. I get the length as 96.
