A farmer has a rectangular field that measures 100 feet by 150 feet. He plans to increase the area of the field by 20%. He will

aliya0001 [1]

Answer:

(100 + x) x (150 + x) = 18,000 ft^2

Step-by-step explanation:

area of a rectangle = length x width

Area of the original field = 15,000

Area after 20% increase = 1.2 x 15,000 = 18,000

Increase i length = 100 + x

increase i width = 150 + x

Area = (100 + x) x (150 + x) = 18,000 ft^2

For the quadratic equation x2 + 2x + 8 = 0, find the value of the discriminant. Then, describe the number and type of roots for

stepladder [879]

ax^2 +bx+c=0
X^2 + 2x+8=0 so a=1, b=2, c=8

Discriminat= b^2 -4ac=2^2 -4•1•8=4-32=-28

So there are no real number solutions, yet there are complex numbers solutions.

Solutions=(-b+- sqrt (discriminant))/2•a
=(-2+-i sqrt ( 2•2•7))/2
Solutia 1= -1 + i sqrt7
Solutia 2= -1 - i sqrt 7
