Answer:
Solve equations of the form a x 2 + c = 0 by extracting the roots. Extracting roots involves isolating the square and then applying the square root property. After applying the square root property, you have two linear equations that each can be solved.
Step-by-step explanation:
Answer:
3/4 or .75
Step-by-step explanation:
.009
---------
.012
Multiply the top and bottom by 1000 to clear the decimals in the fraction
.009*1000
---------
.012*1000
9
-----
12
Divide the top and bottom by 3
3
----
4
In decimal form = .75
The area of the first one would be the area of the rectangle minus the area of the circle, so 18*8 - (pi*3*3). That's equal to around 115.7257 inches squared.
The area of the second one would be the area of the triangle plus the area of the semicircle, so [(4*5)/2]*[(pi*2*2)/2]. That would be 20pi, or around 62.8319 ft squared
I'm not sure about the third one. Is it a trapezoid?
