Answer:
{ - 2, 1 }
Step-by-step explanation:
To determine the values let y = 0, that is
(x + 2)(2x - 2) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 2 = 0 ⇒ 2x = 2 ⇒ x = 1
The set of values are { - 2, 1 }
Answer:
x = 10
Step-by-step explanation:
If S is between R and T, then RS + ST will be equal to RT.
See image.
Use this idea to write an equation.
2x + 3 + 4x = 63
Combine like terms, Subtract 3, Divide by 6, to solve for x. See image.
Using the exterior angle of a polygon theorem, the value of the missing angle is 58°
<h3>Calculating the value of a missing angle </h3>
From the question, we are to calculate the value of the missing angle.
From the given information, the missing angle is (3x -2)°.
To calculate the value of the missing angle,
First, we will determine the value of x
From the <em>Exterior angle of a polygon theorem</em>, we can write that
90° + (3x + 12)° + (4x - 10)° + (3x - 2)° + 70° = 360°
(3x + 12)° + (4x - 10)° + (3x - 2)° = 360° - 70° - 90°
3x° + 12° + 4x° - 10° + 3x° - 2° = 200°
10x° = 200° + 2° + 10° - 12°
10x° = 200°
x = 200/10
x = 20
The missing angle is (3x -2)°
Substitute the value of x
(3(20) -2)°
= (60 -2)°
= 58°
Thus,
The missing angle measure is 58°

Answer:
2x^3 - 3x^2 + 7x - 3
Step-by-step explanation:
Area = length * width
= (2x - 1)(x^2 - x + 3)
= 2x(x^2 - x + 3) - 1(x^2 - x + 3)
= 2x^3 - 2x^2 + 6x - x^2 + x - 3
= 2x^3 - 3x^2 + 7x - 3
