63 x 38 = 2394
63 x 10 = 630
600 x 3 = 1800
30 x 3 = 90
1800 + 90 = 1890
63 x 2 = 126
630 - 126 = 504
1890 + 504 = 2394
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
Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
