width (w) = w
Length (L) = 3w + 4
Area (A) = L x w
25 = (3w + 4)w
25 = 3w² + 4w
0 = 3w² + 4w - 25
w = 
w ≈ 2.3, w ≈ -3.6 (width cannot be negative!)
w ≈ 2.3
Length (L) = 3w + 4 = 3(2.3) + 4 = 6.9 + 4 = 10.9
Answer: width=2.3, Length=10.9

Answer:
The triangle and the square have the same area because they both have four squares
Step-by-step explanation:
The square has four that are easily shown but the triangle has one full one but when two are split together like some of them when you put the two together they equal one whole.
Have a wonderful day/night/afternoon
Step-by-step explanation:
9x+18 < 9-15
1)9-15= -6
9x+18 < -6
9x+18= -5
9x= (-5) - 18
9x= -23
x= 23/9=2 5/9
X=2,55556
5.5 × 2= 11
11 is the length.
perimeter= 11+11+5.5+5.5
The perimeter is 33 units.
