How do you solve this?

Answers

$Solve\ x^4-13x^2=-36.$

View this equation as a quadratic like so:
$x^2(x^2)-13x(x)+36=0$

We can factor just like a normal quadartic!
We want two numbers that multiply to 36x² and add to -13x.
These numbers are -9x and -4x.
Because our leading coefficient is 1, we can factor straight to (x²-4)(x²-9).
Here's what it would look like if we split the middle and factored:
$x^4-9x^2-4x^2+36=0\nx^2(x^2-9)-4(x^2-9)=0\n(x^2-4)(x^2-9)=0$

Of course, any value which causes either factor to equal zero is a solution.
The other factor times zero is still going to be zero, of course.
Let's derive these two possibilities from our equation.
$x^2-4=0,\ or\ x^2-9=0$
We can add that constant to the right side...
$x^2=4,\ or\ x^2=9$
And take the square root of each side.
$\boxed{x=\pm2\ or\ \pm3}$

So, your possible x values are
2, -2, 3, and -3.

x⁴-13x²+36
(x²-4)(x²-9)

x²=4. | x²=9
x=√4. |x=√9
x=2. |x=3

27x³-8=0
x³=8/27
x=2/3

Six more than the quotient of four and a number x

Answers

Break the words down. “Six more” means +6. “The quotient of 4 and x” is 4/x. So, the equation becomes 4/x +6 or (4/x)+6. Hope this helped!

The answer is C. and you did have it right :3 haha as u can see

What is the area of the shaded region to the nearest tenth of a foot?Part a) Explain what formulas you will use to find the area of the shaded area.

Par b) Explain how you find the area of the shaded region. What was your thought process?

Answers

a) The shaded region is that portion of the rectangle that is not in the circle. You need the formulas for the area of a rectangle and a circle.
Area of rectangle = length*width
Area of circle = (π/4)*diameter²

b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
Shaded Area = Area of rectangle - Area of circle
Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²
