4/11 because it is divisible by seven
N*x*a=n+x+a
<span>If n=1, x=2 and a=3.</span>
Answer:
3 inches
Step-by-step explanation:
(14+2x) × (15+2x) = 2(14×15)
210 +30x +28x + 4x² = 420
4x² + 58x - 210 = 0
2x² + 29x - 105 = 0
2x² + 35x - 6x - 105 = 0
x(2x + 35) - 3(2x + 35) = 0
(x - 3)(2x + 35) = 0
x = 3, -35/2(not possible)
-9/5 or -1.8
2 - - 3 = 5
-5 - 4 = -9
