Answer:
C
Step-by-step explanation:
The area of a circle is pi * r^2. The radius is 7 because the diameter is 14 so the radius is 14/2. The square of 7 is 49. Pi is approximately 3.14, so 49 * 3.14 is about 154.
Answer: 200 square units
Step-by-step explanation:
first you think what 60/3 is and you get 20
then you multiply 20x20 and get 400
then you divide by 2 because to find the area of a triangle you use the formula (lxh)/2
Answer:
512 meters
Step-by-step explanation:
the rate or speed given to you is 32 meters per second
the time given to you is 16 seconds
to find the distance, you multiply your rate and time (not add)
multiplying would get you to 512 m/s
Answer:
C. 437 mm^2
Step-by-step explanation:
Area = 1/2bh
A = 1/2(38*23)
A = 437
Answer:
A
Step-by-step explanation:
The form (2x-3)(5x+9) is fully factored. To determine if it is equivalent, multiply the parenthesis out.
(2x-3)(5x+9) = 10x² - 15x + 18x - 27 = 10x² + 3x - 27
Yes this is equivalent.
The solution is A.
