Answer: 36
Step-by-step explanation:
Equation: 12=6+x; x^2
1. Solve for x. X=6
2. Find x^2 or 6^2= 36.
By definition the area of a rectangle is:
A = w * l
The perimeter is:
P = 2w + 2l
Where,
w: width
l: long
Substituting values:
300 = w * l
80 = 2w + 2l
Solving the system of equations we have:
l = 30 m
w = 10 m
Answer:
The length and width of the field are:
l = 30 m
w = 10 m
Answer:
Part A
Eagle = 6 lbs * 60%
= 6 * 0.6
= 3.6 pounds
Bear = 105 lbs * 25%
= 105 * 0.25
= 26.25 pounds
3.6 + 26.25 = 29.85 pounds
Part B
Percent Increase = Change/Original * 100
= 10/105 * 100
= 9.52%

Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
