15x+12y+22+3w-2y+3x+14-12+3w original = 15x+3x+12y-2y+3w+3w+22+14-12 group = 18x+10y+6w+24 answer
3w + 12
7+3w-13x
3w + 4e + 7w - e3 = 10w - e
This is an example of the "commutative" property.
twice length + twice width = perimeter In this example, L= 3W 2(3W)+2(W)=64 8W=64 W=6 L =3W L=18 The dimensions of this rectangle are: 18 by 6
no
It will be three times the size. Each length will be multiplied by 3.. Perimeter = h+h+w+w if we multiply each by three then we get 3h+3H+3w+3w = 3P
given: 4w+(6k-3w)+(2-k)remove parentheses: 4w+6k-3w+2-kcollect like terms: 4w-3w+6k-k+2simplify: w+5k+2
3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
l=3w Perimeter (p) = 2*(l+w) = 56 2*(3w+w)=56 2*4w=56 8w=56 w=7 inches l=3w = 3*7 = 21 inches
