The surface of the rectangular prism is 18, because you just add up all of your sides
Answer:
When an object has been transformed, its image can again be transformed to form a new image. Such transformation is called a combination of transformations. After a combination of transformations, the change from the single object to the final image can be described by a single transformation.

The number of solutions in the equation is (b) two real solutions
<h3>How to calculate the number and type of solutions?</h3>
The quadratic equation is given as
-5x2 + 4x + 1 = 0.
Rewrite properly as
−5x² + 4x + 1 = 0
The discriminant of a quadratic equation is calculated using
d = b² - 4ac
In the equation −5x² + 4x + 1 = 0, we have
a = -5, b = 4 and c = 1
Substitute a = -5, b = 4 and c = 1 in d = b² - 4ac
So, we have
d = (4)² - 4 * (-5) * (1)
Evaluate
d = 36
Because the discriminant is greater than 0, the equation has two solutions and the type of solution is real solution
