Assume you mean 3x^2 when you typed the question.
3x^2+14x+16=0
(3x+8)(x+2)=0
x=-8/3 or -2
Answer:
A
Step-by-step explanation:
v - 2u
= < - 2, 4 > - 2 < 2.5, - 4 > ← multiply each component by 2
= < - 2, 4 > - < 5, - 8 > ← subtract corresponding components
= < - 2 - 5, 4 + 8 > = < - 7, 12 >
Graph A shows the resulting vector

Answer: It has systematic sampling.
Step-by-step explanation:
Systematic sample is a method of statistics which includes the selection of elements from the ordered sampling.
It has equal probability of each element.
It is done by choosing the starting point and selecting other elements after fixing the systematic or periodic interval.
She randomly selects the sixth name as a starting point and then selects every 100th subsequent name (106, 206, 306, etc.)
So, Sixth name is the starting point and then choosing the other elements after fixing an interval of 6.
So, it has systematic sampling.
