21 m 6 cm
15 + 2(3 + 4) 15 + 2(7) 15 + 14 Answer is 29.
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
4 + 15 - 2 = 17
The answer is 15.
3 + 2(4 + 2) =3 + 2(6) = 3 + 12 = 15
4/5 + 2/15 = 14/15
It is: 2/3 plus 4/5 = 22/15
2/5 = 6/15 + 4/15 = 10/15 = 2/3
(4 times 3) plus 2 plus 1
15 x (8/4) + 2 = 15 x 2 + 2 = 32
No, 1 + 2 + 3 + 4 + 5 = 15.
15. lol
