Answer:
a. x² + 6x + 9 = -22 + 9
Step-by-step explanation:
they moved the 22 to the right by subtracting it. this leaves a binomial on the left side, which if what you want to solve it.
then they completed the square by dividing b (6) by 2 = 3. then squaring 3 to get 9.
if you added 9 to the left, then you have to add 9 to the right, therefore resulting in -22 + 9.
3(x+7)+3(x+3)-4(x+3)
3x+21+3x+9-4x-12
2x+18 or 2(x+9)
1/3 ( 3x - 1) = -1/5 - 2/5
1/3 (3x - 1) = -3/5
3x - 1 = -3/5 (3)
3x - 1 = -9/5
3x = -9/5 + 1
3x = -9/5 + 5/5
3x = -4/5
x = -4/15
First, multiply the # of points he scores a game by the # of games in the season:
18x14= 252points
2*5+5*3+2*3. (10)+(15)+(6)=31.
