We actually need the choices but oh well, we can simpify and hopefuly it is one of the choices
remember the distributive property
a(b+c)=ab+ac
so
7(p+2n)+n
distribute first
7(p)+7(2n)+n
7p+14n+n
7p+15n is an equivilent expression
Sorry about all the arrows, but hope this helps! Reels=$21 and rods=$80. All my work is shown.
The question already has all the information's that are required for getting to the solution. It is important to minutely look at all the details provided.
Actual price of the item = $14.74
Percentage of sales tax that needs to be added = 4%
Then
Amount of sales tax that needs to be added = (4/100) * 14.74 dollars
= 58.96/100 dollars
= 0.5896 dollars
= 0.59 dollars
Then
The cost of the item including sales tax = (14.74 + 0.59) dollars
= 15.33 dollars
From the above deduction we can easily conclude that the correct option among all the options given in the question is option "B".
It should be 23/99
23/99= 0.232323...
23/999= 0.023023023....
2/9= 0.222222....
Final answer: 23/99
Answer:
3(f - 9)(f + 4)
Step-by-step explanation:
Assuming you require to factorise the expression
3f² - 15f - 108 ← factor out 3 from each term
= 3(f² - 5f - 36) ← factor the quadratic
Consider the factors 0f the constant term (- 36) which sum to give the coefficient of the f- term (- 5)
The factors are - 9 and + 4 , since
- 9 × 4 = - 36 and - 9 + 4 = - 5 , then
f² - 5f - 36 = (f- 9)(f + 4)
Then
3f² - 15f - 108 = 3(f - 9)(f + 4)
