A= 3, b= 14 c= -5
To find this, use the foil method of first, outside, inside, and then last. By doing so you’ll get the answer of 3x^2 + 14x -5
Answer: 7
Step-by-step explanation:
First find the absolute value of the numbers then apply the signs.
The absolute value of -5 is 5
The absolute value of 6 is 6
The absolute value of 8 is 8
5 - 6 + 8 = 7
Answer:
5 games
Step-by-step explanation:
Do 80% of 25 which would be 20 and then you can determine how many they lost so if they won 20 games and they have 25 games total then they lost 5 games.
Answer:
B
Step-by-step explanation:
In A, it says that 9s +7c can be lower or equal to 160. This is wrong.
In C, it says that 9s +7c can only be higher than 160, when the question says at least, which means it can also be equal to 160, making it wrong.
In D, it says that 9s +7c can be lower or equal to 20. This is wrong.
Through elimination, only B can be right.
If
is a root of the equation, q(x) = 6x3 + 19x2 – 15x – 28 then by the factor formula q(
) = 0; if that is not the case then
cannot be a factor of the function.
Now, q(
) = 6(
)³ + 19(
)² – 15(
) – 28
=
Therefore Yuri, since q(
) ≠ 0 then it implies that
is not a root of q(x).
Additionally, a root should be expressed in terms of x, thus the possible root ought to be written as x =
, instead of just
