Answer: x = 5

------------------------------------------
------------------------------------------

Explanation:

We have a right triangle as indicated by the square angle marker. Two of the sides are known: specifically the hypotenuse (13) and one of the legs (12). The other leg (x) is unknown.

We can use the Pythagorean Theorem to find x

a = 12 is one of the known legs
b = x is the unknown leg
c = 13 is the hypotenuse

Pythagorean Theorem:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
144 + x^2-144 = 169-144 ... subtract 144 from both sides
x^2 = 25
sqrt(x^2) = sqrt(25)  ... apply square root to both sides
x = 5 

Side Note: Keep in mind that x can't be negative so it doesn't make sense to use the plus/minus here. We'll only stick with the positive version.

What is the sum of the polynomials?
Nadya [2.5K]

For this case we have the following polynomials:

-x ^ 2 + 9\\-3x ^ 2 - 11x + 4

Adding the polynomials we have:

(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)

Rewriting we have:

x ^ 2 (-1-3) - 11x + (9 + 4)

Therefore, the result of the sum is:

-4x ^ 2 - 11x + 13

Answer:

the sum of the polynomials is:

-4x ^ 2 - 11x + 13

option 2
