Can someone help with this 15x plus 12y plus 22 plus 3w-2y plus 3x plus 14-12 plus 3w?
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
What is equivalent to 6w plus 5 - 3w plus 7?
3w + 12
What is 2 plus 3w-13x plus 5?
7+3w-13x
What is 3w plus 4e plus 7w-3e?
3w + 4e + 7w - e3 = 10w - e
5 plus 3w plus 2 equals 5 plus 2 plus 3w which mathematical property?
This is an example of the "commutative" property.
A rectangle has a length three times its width The perimeter is 64?
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
Is this a binomial 3w plus 1?
no
What happens to the perimeter when a rectangle is enlarged by a scale factor of 3?
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
What is 4w plus 6k - 3w plus 2 - k?
given: 4w+(6k-3w)+(2-k)remove parentheses: 4w+6k-3w+2-kcollect like terms: 4w-3w+6k-k+2simplify: w+5k+2
3w- plus 2 equals 2w plus 3?
3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
A rectangle has length three time its width if the perimeter of the rectangle is 56 inches what is the length of the rectangle?
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
What is 4y plus 3w plus 4x plus 9y plus 7x-7w?
4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
