Answer:
x = -2
x= -3
Step-by-step explanation:
x 2+5x+6=0
To solve the equation, factor x^2+5x+6 using formula x^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=5
ab=6
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 6.
1,6
2,3
Calculate the sum for each pair.
1+6=7
2+3=5
The solution is the pair that gives sum 5.
a=2
b=3
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x+2)(x+3)
To find equation solutions, solve x+2=0 and x+3=0.
x=−2
x=−3
Answer:
Part A $150.00
Part B $140.00 because you would do 35 x 4 = 140.
Part C, He will have $17 left over. You would take 167 - 140 = 17
Question 5, The would have gathered $150 because you would take 30 x 5 = 150.
Answer:
<h2>(a) 5</h2><h3>> 5 is greater than 4</h3>
Answer:
8,5,2
Step-by-step explanation:
8 , 5, 2 Just use rigorous trial and error
Answer:
6
Step-by-step explanation:
let the number be x
(x-2)3=x+6
3x-6 = x+ 6
2x= 12
x= 6
