Answer:
x^2 -2x + 1
Step-by-step explanation:
Think of a quadratic equation as
ax^2 + bx + c
x^2 -2x +
Comparing the two equations
a = 1 , b = -2, c = ?
c becomes the missing part
Divide b by 2
-2/2 = -1
square the result
-1^2
= 1 this is what to add to get a perfect square
x^2 -2x + 1
(x - 1)^2
So you just subsitute -3 for x
f(-3)=-(-3)+15
f(-3)=3+15
f(-3)=18
answer is C
18
Given: Different points and an angles as found in the image

Answer: 57.5%
Step-by-step explanation:
Because....
23/40 =
23 ÷ 40 =
0.575 =
0.575 × 100/100 =
0.575 × 100% =
(0.575 × 100)% =
57.5%
* <em>Therefor, the correct answer would be 57.5% .</em>
