Answer:
y = 2(x - 2)² + 3 vertex form
y = 2x² - 8x + 11 standard form
Step-by-step explanation:
Vertex form
y = a(x - h)² + k
(h, k) = (2, 3)
y = a(x - 2)² + 3
To find "a" plug in the y-intercept (0, 11)
11 = a(-2)² + 3
11 = 4a + 3
Subtract 3 from both sides
8 = 4a
a = 2
y = 2(x - 2)² + 3
Expand
y = 2(x² - 4x + 4) + 3
y = 2x² - 8x + 11

Answer:
10m×1.5m=15m squared total area of the wall
15×100=1500
1500÷200=7.5 bricks would be needed for that wall.
(8.4n+2n)= 10.4n thats for the left side. Then u are left with, 10n =2. Then 2/10 that means that n =.2
4 3/10 because you can turn two over five into 4/10 so to make -1 3/10 to -2 you -7/10 then -3 to get -5 then -6/10 to get -5 4/10
