  • Answer:

<em>86.20 ft²</em>

  • Step-by-step explanation:

<em>Hi there !</em>

<em>A = A₁ + A₂</em>

<em>A₁ =semicircle</em>

<em>A₁ = πr²/2</em>

<em>r = d/2 = 6.4ft/2 = 3.2 ft</em>

<em>A₁ = 3.14×(3.2ft)²/2 ≈ 32.15 ft²</em>

<em />

<em>A₂ =  trapezium</em>

<em>A₂ = (b + B)×h/2</em>

<em>A₂ = (5.1ft + 6.4ft)×9.4ft/2 = 54.05 ft²</em>

<em />

<em>A = 32.15 ft² + 54.05 ft² = 86.20 ft²</em>

<em>Good luck !</em>

The answer is 3.10 because the 4 is in the hundredths place and if it’s 5 or more it would be 3.20 but in this case it’s lower than 5 so it would be 3.10

Solve x 2 + 9x + 8 = 0 by completing the square. What are the solutions?
Sindrei [870]

So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: x^2+x+8x+8=0

Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: x(x+1)+8(x+1)=0

Now you can rewrite the equation as (x+8)(x+1)=0

Now using zero product property, solve for x:

x+8=0\\ x=-8\\ \\ x+1=0\\ x=-1

<u>In short, the solutions are {-1,-8}, or C.</u>
