Answer:</h3>
The real solutions are -5, -4, 4, 5. There are no complex solutions.
<h3>
Step-by-step explanation:</h3>
The equation ...
... x^4 -41x^2 +400 = 0
can be factored as ...
... (x^2 -16)(x^2 -25) = 0
... (x -4)(x +4)(x -5)(x +5) = 0
So, all roots are real and are ...
... x ∈ {-5, -4, 4, 5}
_____
These are the values of x that make the factors zero.
Step-by-step explanation:
If you want to know how to find the area of a trapezoid, just follow these steps.
Identify the length of both bases. The bases are the two parallel sides of the trapezoid. Let’s call them sides A and B. Suppose A is 8 in long and side B is 13 in long.
Add the lengths of the bases. Add 8 in and 13 in. 8 in + 13 in = 21 in.
Identify the elevation of this trapezoid. The height of the trapezoid is vertical to the bases. In this case, assume the elevation of the trapezoid is 7 in.
Multiply the amount of the lengths of the bases by the elevation. The amount of the lengths of these foundations is 21 in and the height is 7 in.
Divide the result by 2. Split 147 in2 by 2 to find the last answer. 147 in2/2 = 73.5 in2. The area of the trapezoid is 73.5 in2.

I think its like you divide 64 by 4. This will tell you how many sets of the 4 yards you have which is important to know since each 4 yards equals 7 inches. 64 divided by 4 is 16. Then multiple 16 by 7 since there's 16 sets of 4 and each set is 7 inches. This will come to a total of 112 inches.
I hope this helps, sorry if its wrong I haven't done this in a while, but I'm pretty sure its correct
