Answer:
7,11
Step-by-step explanation:
The width is x. x+4= the length. The area is side times side, so it’s
x × (x+4) = 77
We can simplify this to:
x × x + x × 4 = 77
x^2 + 4x = 77
x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:
x = 
->
That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11
A. P[TTTTH] = .55^4*.45 = .0412
