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
2. 22
6. 12
7. 420x^3
10. 7
14. 1
1 pound is 16 ounces so multiply by .30 to get 4.80 times 2 bc theres 2 pounds which will be $9.60
