3w -6 = -15 3w = -15+6 3w = -9 w = -3
(3w(3w)/3w) + 5
To solve the equation 3w + 4 = 24, you first need to isolate the variable w. Subtract 4 from both sides to get 3w = 20. Then, divide both sides by 3 to find the value of w. Therefore, w = 20 / 3 = 6.6667 (rounded to four decimal places).
3+w is the simplest expression of this problem.
3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
Expressed as an algebraic equation, this would equal 3w.
3w
Width = 'W'. Length = '3W'. Perimeter = 2 (Length + W) = 2 (3W + W) = 2 (4W) = 8W = 48 W = 6 inches and Length = 18inches Area = (Length) x W = 108 sq in============================ Easier way: Width = W, Length = 3W Area = (W) x (3W) = 3W2 We showed above that W = 6 3W2 = 3 x 36 = 108 in2
If: 3w = 42 Then: w = 14
3w -6 = -15 3w = -15+6 3w = -9 w = -3
(3w(3w)/3w) + 5
3w^2 - 8w + 4 = (3w -2) (w-2) So 3w-2=0, then 3w=2, so w=2/3, w-2=0, so w=2. Your solutions are w=2/3 and w=2.
L = 3W - 6; L x W = 360; Substitute: (3W - 6) x W = 360 ie 3W2 - 6W - 360 = 0 this factorises as (3W + 30)(W - 12) ie the positive value of W is 12 ft and L is 30 ft.
w2-3w = 0 w(w-3) = 0 w = 3 or w = 0
If: 3w-17 = 4 Then: w = 7
Area = L x W. L = 3W - 8 so A = 3W2 - 8W or W(3W - 8)
Area = w2 - 6w + 9 = w2 - 3w - 3w + 9 = w(w-3) - 3(w-3) = (w-3)(w-3) It is clear after factorizing that the area given is of square of side: w-3 So, perimeter = 4 x side = 4 x (w-3) = 4w-12 units
