Answer:
x1= -4
x2 = 4
Step-by-step explanation:
Set the equation equal to zero
x2 − 16 = 0
then
(x + 4)(x − 4) = 0
(x+4)= 0 which is equal to -4
and
(x-4)= 0 equals 4
Answer:
AB = 14 units
∠F = 39°
Step-by-step explanation:
Given:
ΔABC ≅ ΔDEF
So,
AB = ED (By CPCT)
So,
AB = 14 units
∠C = ∠F (By CPCT)
∠F = 39°
If by bivariate data you mean data in charts or any type of collection of data, the data's would be proportional and would be a straight line and go through the origin in a coordinate plane.
