Answer:
2√3
Step-by-step explanation:
Multiply these binomials in the usual way:
(1 +√3)(3 -√3) = 1(3 -√3) +√3(3 -√3)
= 3 -√3 +3√3 -3 = (3 -3) +√3(-1 +3)
= 2√3
Answer:
your answer is C) A negative radius does not make sense.
Step-by-step explanation:
hope it helps ^_^
This is for A part A: It shows that the least amount is 37.5 minutes
It shows the most amount of time is 60 minutes
One thing it does not show is how many students where in the class.
Okay, first we need to calculate the area of the rectangle.
Area of Rectangle- 16 x 6 = 96
Next, we need to calculate the area of the semicircles.
Formula: Radius x Radius x pi (3.14) = Area of circle
Since we know that the diameter is 6 we can figure out the radius.
The radius is half of the diameter. So our radius is 3.
3 x 3 x 3.14 = 28.26
Since it's a semi circle we now need to divide by 2.
28.26 divided by 2 = 14.13
Then, we add.
Area of rectangle
+
Area of 2 semi circles
96 + 14.13 + 14.13 = Total Area of The Figure
So our answer is 124.26
