Answer:
2x^2 + 11x - 6
b = 11
Step-by-step explanation:
To write the equation in standard form, use the distributive property to multiply. Then combine like terms.
(2x - 1)(x + 6)
2x^2 - x + 12x - 6
2x^2 + 11x - 6
Now written in the standard form of a quadratic ax^2 + bx + c, the value of b here is 11.
Answer:
The third one
Step-by-step explanation:
I hope I've helped you.
Explanation:
This can be explained by thinking numbers on the number line as:
Lets take we have to multiply a positive number (say, 2) with a negative number say (-3)
<u>2×(-3)</u>
Suppose someone is standing at 0 on the number line and to go to cover -3 , the person moves 3 units in the left hand side. Since, we have to compute for 2×(-3), The person has to cover the same distance twice. At last, he will be standing at -6, which is a negative number.
A image is shown below to represent the same.
<u>Thus, a positive times a negative is a negative number.</u>
Answer: answer is 4
Step-by-step explanation:
8.4 N - 3.2 P when n equals 2 and P equals 4
Multiply 8.4 by 2 and 3.2 by 4
= 8.4 (2) - 3.2 (4)
Then subtract
= 16.8 - 12.8
=4
