Answer:
9x+2
Step-by-step explanation:
It's a simple problem, to find the perimeter, add a+b+c. In this case, it's with binomials, but it follows the same idea.
(2x+2)+(3x+1)+(4x-1)
2x+2+3x+1+4x-1
Combine like terms.
2x+3x+4x=9x
2+1-1=2
Left with 9x+2 as your perimeter binomial.
Answer:
A is the answer
Step-by-step explanation:
Answer: 2(N+15) = 6N
======
We let N be the number.
Then, "<span>the sum of a number and fifteen" would be
N + 15
Two times this sum would give us
2(N+15) ... you must distribute!
This must be equal to six times the number. Six times the number is 6N, therefore
2(N+15) = 6N</span>
Answer:
As the X values increase the Y values also tend to increase'
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Given
5x - 4 ≥ 12 or 12x + 5 ≤ - 4
Solve each inequality
5x - 4 ≥ 12 ( add 4 to both sides )
5x ≥ 16 ( divide both sides by 5 )
x ≥ 
OR
12x + 5 ≤ - 4 ( subtract 5 from both sides )
12x ≤ - 9 ( divide both sides by 12 )
x ≤ - 
Solution is x ≥ or x ≤ - → A
