Step-by-step explanation:
I cannot read the initial expression without doubt, but I just guess it is 3×sqrt(8).
that would make it : sqrt(9×8) = sqrt(72).
A is correct : sqrt(9)×sqrt(8) = sqrt(9×8) = sqrt(72).
B is correct : sqrt(6)×sqrt(12) = sqrt(6×12) = sqrt(72).
C is NOT correct : sqrt(6)×sqrt(24) = sqrt(6×24) = sqrt(144) = 12
D is correct : sqrt(3)×sqrt(24) = sqrt(3×24) = sqrt(72)
E is NOT correct : 72 is NOT sqrt(72)
F is NOT correct : sqrt(3)×sqrt(12) = sqrt(3×12) = sqrt(36) = 6
The answer would actually be a 110 units because the bottom left corner had 20 units and the bigger square had 90.
Answer:
B) f(x) = 3x² - 2x + 5
Step-by-step explanation:
To find the correct quadratic function that represents the table, you must substitute [x] into the quadratic function.
A) f(x) = 3x² + 2x - 5
B) f(x) = 3x² - 2x + 5
C) f(x) = 2x² + 3x - 5
D) f(x) = 2x² - 2x + 5
A. 3(-2)² + 2(-2) - 5 =
3(4) - 4 - 5
12 - 4 - 5
12 - 9
= 3
B. 3(-2)² - 2(-2) + 5 =
3(4) + 4 + 5
12 + 9
= 21
C. 2(-2)² + 3(-2) -5 =
2(4) - 6 - 5
8 - 11
= - 3
D. 2(-2)² + 2(-2) + 5 =
2(4) - 4 + 5
8 - 4 + 5
8 + 1
= 9
