Step-by-step explanation:
8 square unit
16 square unit
190 acres of soybeans and 110 acres of corn= 300 acres
corn + soybeans =300
corn +110=soybeans
300-110= 190
Answer:
d
Step-by-step explanation:
(a^2)^3 = a^6
from that we get
(x^-3 * y^-12) / (x^15 * y^-15)
which is d
Let the width = x
The length would be 4x-27
Area = length x width
2790 = (4x-27) * x
Expand:
2790 = 4x^2 - 27x
Subtract 2790 from both sides:
4x^2 - 27x - 2790 = 0
Use the quadratic formula to solve for the positive value of x:
X = -(-27) + sqrt(-27^2 -4*4(-2790)) /(2*4)
X = 30
Now replace x with 30 in the lengths:
Width = x = 30 inches
Length = 4x -27 = 4(30) -27 = 120-27 = 93 inches
