Answer: -8x^3y^2 (choice B)
The coefficients multiply to 4 times -2 = -8
the x terms multiply to x^2 times x = x^(2+1) = x^3
The y terms multiply to y times y = y^(1+1) = y^2
So that's how I ended up with -8x^3y^2
B = 18 because 18-5 is equal to 3 and 3x3 is equal to 9.
They are opposite exterior angles
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
