3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Answer:
90
Step-by-step explanation:
It starts going up by 6. Then it goes up by 2 more than six. 6, 8, 10. Going up 2 more than last time. 2018 would be 12 more, or 76, and 2019 would be 14 more, or 90.
Okay so if
4cm:9ft
Than
8cm:18ft
2cm:4.5ft
1cm:2.25ft
Okay so
1•11=11
2.25•11=24.75
The answer is 24.75ft
Answer:
x≥2
Step-by-step explanation:
Answer:
15x^3y+6x^2y^2+9xy^3
Step-by-step explanation:
3xy ( 5x^2 +2xy +3y^2)
Distribute the 3xy to all terms in the parentheses
3xy*5x^2+3xy*2xy+3xy*3y^2
15x^3y+6x^2y^2+9xy^3
