Answer:
A=
Step-by-step explanation:
We are given that John is building a rectangular pen for his sheep.\
We have to complete the given equation
Let w be the width of rectangular pen
According to question
Length of pen=8w+5
We know that
Area of rectangle=
Using the formula
Area of rectangular pen=
Therefore, the area of rectangular pen=A=
Is this a algebra question? I just want to know?
Answer:
y=2/3x-9
Step-by-step Explanation
1.You put 2x-3y=6 into y-intercept to find out the slop, which is 2/3.
2. Put the coordinate pair given into point slop form, which will look like this: y+3=2/3(x-9)
3. Put that into y-intercept (answer)
4. Boom done
Answer:
The roots are +/- 5 and +/- 4i or 5, -5, 4i, -4i
Step-by-step explanation:
Begin by dividing through by - 3
-3x^4 / - 3 + 27x^2/-3 + 1200/-3 = 0
x^4 - 9x^2 - 400 = 0 This makes it easier to work with. Substitute
z = x^2
z^2 - 9z - 400 = 0 Factor
(z - 25)(z + 16) = 0 Put the x^2 back in
(x^2 - 25)(x^2 + 16)
======================
Factor x^2 - 25 using the difference of squares.
(x^2 - 25) = (x + 5)(x - 5)
x = +5 and x = - 5
======================
Factor x^2 + 16
x^2 + 16 = 0
x^2 = - 16 Take the square root of x^2 and -16
x = sqrt(-16)
x = +4i, x = - 4i
Answer
The roots are +/- 5 and +/- 4i
