Answer:

x = <u>22</u>

Step-by-step explanation:

The sum of the angles in a quadrilateral is 360°. This can be written as:

 61° + 115° + 96° + 4x = 360°

Further simply and solve to find the value of x.

 272° + 4x = 360°

 4x = 360° - 272°

 4x = 88

 x = \frac{88}{4}

 ∴ x = 22

shtirl [24]

Answer:

X = -3

Y = -5

Step-by-step explanation:

    2X - 3Y = 9

<u>- (-5X - 3Y) = 30</u>

    7X + 0Y = -21

               X = -3

2(-3) - 3Y = 9  

        - 3Y = 15

            Y = -5

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –
elena55 [62]

Answer:


Step-by-step explanation:

Given is an algebraic polynomial of degree 5.

g(x) = 3x^5-2x^4+9x^3-x^2+12\\

Here leading term is p=3 and constant term is q =12

Factors of p are ±1,±2,±3

Factors of q are \frac{±1,±2,±3,±4,±6,±12} \\

Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12

Hence any other polynomial

g(x) = 3x^5+ax^4+bx^3+cx^2+12

will have same possible zeroes of p/q, when a,b,c are rational.

Hence any polynomial of this type would have the same possible rational roots.
