The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.
<h3>How to find the value associated with a quadratic equation</h3>
In this case we have a quadratic equation (f(x) = - x² + 3 · x + 13) that has to be evaluated at a value of x, that is, x = 10. Now we proceed to show the solution of the exercise step by step:
- x² + 3 · x + 13, x = 10 Given
- 10² + 3 · 10 + 13 Previous step
- 100 + 30 + 13 Definition of power / Definition of multiplication
- 57 Definition of addition and subtraction
The quadratic equation f(x) = - x² + 3 · x + 13 evaluated at x = 10 is equal to - 57.

Answer:
He has 3 $20 and 3 $5
Step-by-step explanation:
20 x 3 = $60
5 x 3 = $15
15 + 60 = $75
Step-by-step explanation:
<y+60+58=180 (angle sum property)
<y+118=180
<y=180-118=62
<ACB+<ACD=180(degree of a line )
58+x=180
x=122
