11. you do 3x3=9 then plus 9+2 = 12 then 12 x 12 = 144
sorry idk 10.
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
Negative correlation refers to an inverse relationship between two variables. When one variable increases, the other decreases.
The variables are latitude and average temperature.
The explanatory variable is latitude and the response is the average temperature. Choice B.
As the latitude increases, the average temperature decreases. This is a strong negative correlation of between the two variables.
Answer: Your answer would be 16y² + 12x - 4y
