Answer:
E.200.5ft²
Step-by-step explanation:
To find the area of the composite figure we simply split it into two regular shapes, a half circle and a square, we then find the area of the two shapes individually and add them together.
Area of square = s² where s = side length
It appears the given side length is 12 so s = 12
Which means area = 12² = 144ft²
For semi circle
Area = 1/2(πr² ), where r is the radius
The side length of the square is shared with the diameter of the semi circle meaning that the diameter of the semi circle is 12
To convert to radius from diameter we simply divide by 2 so r = 12/2 = 6
We have area = 1/2(πr² ) and r = 6
So area = 1/2(π6²)
==> evaluate exponent
Area = 1/2(36π)
==> take one half of 36
Area = 18π
==> multiply 18 and π
Area = about 56.5
Finally we add the two areas together
Total area = 56.5 + 144 = 200.5ft²
Answer:
v = -5
Step-by-step explanation:
Step 1: Write out equation
-8 + 5v = -33
Step 2: Add 8 on both sides
-8 + 8 + 5v = -33 + 8
5v = -25
Step 3: Divide both sides by 5
5v/5 = -25/5
v = -5
Answer:
The trinomial 
is not a perfect square trinomial because the third term is not a square.
Step-by-step explanation:
A trinomial is an expression composed of three terms that are joined together by addition or subtraction.
A perfect square is created when a value is multiplied times itself. Thus, 
, making the trinomial a² + 2ab + b² a perfect square.
To show that a trinomial is a perfect square you must show that if the first and third terms are squares, figure out what they're squares of. Multiply those things, multiply that product by 2, and then compare your result with the original quadratic's middle term. If you've got a match (ignoring the sign), then you've got a perfect-square trinomial.
The trinomial is not a perfect square trinomial because the third term is not a square.
