Answer:
16x -2
Step-by-step explanation:
You know how to compute the perimeter of a rectangle of length L and width W:
P = 2(L+W)
Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.
P = 2((5x-2) +(3x+1))
P = 2(8x -1)
P = 16x -2 . . . the perimeter of the rectangle
Answer:
the answer is 40
Step-by-step explanation:
x+60
x=60-20
x=20
3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
When adding fractions you need to get common denominators then you multiply too times bottom and then boom add and there you go
