Because this is an equiangular triangle, we can set any two sides equal to each-other to solve for x, because all sides are the same length.

5x - 22 = 4x - 10

Subtract 4x from both sides.

x - 22 = -10

Add 22 to both sides.

x = 12

<h3>The value of x is equal to 12.</h3>

form a polynomial function whose real zeros are -2 with multiplicity 2 and 4 with multiplicity 1 whose degree is 3
NeTakaya

Answer:

f(x) = {x}^{3}  -12x - 16

Step-by-step explanation:

We want to for a polynomial function whose real zeros are -2 with multiplicity 2 and 4 with multiplicity 1.

If -2 is a zero of a polynomial, then by the factor theorem, x+2 is a factor.

Since -2 has multiplicity 2, (x+2)² is a factor.

Also 4 is a zero which means x-4 is a factor.

We write the polynomial in factored form as:

f(x) =  {(x + 2)}^{2} (x - 4)

We expand to get:

f(x) = ({x}^{2} + 4x + 4)(x - 4)

We expand further to get:

f(x)=x({x}^{2} + 4x + 4) - 4({x}^{2} + 2x + 4)

f(x) = {x}^{3} + 4 {x}^2 + 4x  - 4 {x}^{2} + 8x - 16

f(x) = {x}^{3} - 12x - 16

There should only be 1, -8, because the “higher” the negative number is, the less it actually is. That makes -8 less than -4
