Answer:
8
Step-by-step explanation:
The polynomial is of degree 4·2 = 8, so there will be 8 roots. All of them will be complex.
4, 8, 10, 7, 3, 4... Those r in order from top to bottom! it's all about the simplification!
First, you need to collect the like terms; 7x + (-20 - 90). Next simplify; 7x - 110
answer; 7x - 110
0.123, 2.13, 2.31, then 3.12. Hope this helps. :)
We can solve this problem using the Pythagorean Theorem. The Pythagorean Theorem states, that with hypotenuse c, and legs a and b, a² +b² = c², and since this is a right triangle, that principle is true here. In this problem, we have the length of the hypotenuse and leg a. So, we can insert the values of the variables and then simplify to find out the length of b. 15²+b²=20²b²=400-225b²=175b=√175
