thank you so much @Reiny
here are the questions
17. A bag contains 10 white golf balls and 6 striped golf balls. A golfer wants to add 112 gold balls to the bag. He wants the ratio of white to striped golfballs to remain the same. How many of each should he add?
18. The coordinates of quadrilateral VWXY are given below. Find the coordinates of its image after a dilation with the given scale factor
V((6,2), W(-2,4), X(-3,-2), Y(3,-5), scale factor of 2
19. Tell whether the pair of polygons is similar. Explain why or why not.
PQ - 8ft
QR - 13ft (this is for the bigger polygon)
RS - 8ft
SP - 13 ft
(then it goes to the smaller polygon which is..)
TU - 5.2 ft
UV - 2.4
VW - 5.2
WT - 2.4

2. 3x^2+6-2x+5x-4x^2+9
a. -x^2+3x+15
b. 7x^2+3x+3
c. x^2-3x+15
d. -x^2+7x+15
First we simplify the polynomial by combining the like terms.
3x^2 - 4x^2 - 2x + 5x + 6 + 9 = -x^2 + 3x + 15
Therefore, the answer is (a) -x^2+3x+15.
3. 4x^2+8x-11x+6-5x^2+2
a. -x^2-3x+8
b. -x^2+3x+8
c. x^2-3x+8
d. x^2+3x+8
First we simplify the polynomial by combining the like terms.
4x^2 - 5x^2 + 8x - 11x + 6 + 2 = -x^2 - 3x + 8
Therefore, the answer is (a) -x^2-3x+8.
