Answer: A coefficient refers to a number or quantity placed with a variable
Step-by-step explanation: For example, in the expression 3x, 3 is the coefficient but in the expression x2 + 3, 1 is the coefficient of x2. In other words, a coefficient is a multiplicative factor in the terms of a polynomial, a series, or any expression.
Answer:
No
Step-by-step explanation:
Substitute by x = 2 and y = - 1
You will get 2*2 + (-1) = 3 not 5
Then it doesn't lie
B since you can rewrite it as (2x+7)(x-4)=0 and you can solve it and you get B
The answer is o+ Hope this helped.
