Option D: 
is the solution
Explanation:
The given expression is 
We need to determine the factors of the expression by grouping.
The solution can be determined by factoring the common terms in the expression.
Let us group the expression.
Let us factor out the common terms from the two groups.
Thus, we have,
Thus, the factors of the expression is
Unless there is no promotion like "buy 2 get 1 free" or "buy 2 get 1 for 50%" etc. then the cost of ordering multiple items is always proportional. Let's say something costs $5. Two items will cost $10, three $15, four $20 etc. These numbers are all proportional. Hopefully that's what you meant :)
Answer:
, 
Step-by-step explanation:
you use the quadratic equation: (-b ± 
) ÷ 2a
in this case, a = 5, b = 5, c = 8
inside the radical will be -135, hence using 135i where 'i' equals -1
Carmen is 6 and jaun is 18 because 6. Times 3 equals 18 and if you add 6 to 18 you will get 24
Answer:
x=-1
Step-by-step explanation:
0.5(5−7x)=8−(4x+6)
I do not like working with fractions so I will multiply by 2 on each side
2*0.5(5−7x)=2*8−2(4x+6)
5 -7x = 16 -2( 4x+6)
Distribute
5-7x = 16 -8x -12
Combine like terms
5-7x =4-8x
Add 8x to each side
5 -7x+8x = 4-8x+8x
5+x = 4
Subtract 5 from each side
5-5+x = 4-5
x =-1
