X^4 - 16 = 0
Is factoring by polynomials

(x-4)(x+4)

Step-by-step explanation:

This is a special case. Eventually, it will be helpful to memorize these, but for now, this special case is (a-b)(a+b)=(a^2)-(b^2). In this case, a=x and b=4 because the square root of 16 is 4. Plug in your numbers and then you have: (x-4)(x+4) which is your answer!

I hope this helped! :)

If your looking for a true or false answer because I didn't know what type of problem that you were asking, the answer is false because you haven't factored the equation, if anything, you simplified it. factoring would be what we did above.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
