B. x^2 + 5x - 4 = 0
Anyway that you try to factor it will not work
~~hope this helps~~
Answer:
Step-by-step explanation:
4b - 6d = 4*7 - 6*3
= 28 - 18
= 10
I don’t have time to explain it but hopefully someone else will, he answer is -13!
Answer: 
Step-by-step explanation:
The consecutive numbers are the numbers which come one after another .
Using Algebraic expressions
Let x be the first number , then the second number would be x+1 and the third number would be x+2.
The given statement : The sum of three consecutive integers is 765.
According to this statement , the equation will become :

Therefore, the equation that describes the statement would be :
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
