Answer:
(2x + 1)(x + 5)
Step-by-step explanation:
2x² + 11x + 5 =
= 2x² + 10x + x + 5
= 2x(x + 5) + (x + 5)
= (2x + 1)(x + 5)
Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
Answer: A
Given:
Number of flower pots = 6
To find:
The number of ways of the gardener to arrange the flower pots.
Solution:
Number of ways to arrange n items is n!.
So, the number of ways to arrange 6 pots is:
Therefore, there are total 720 ways of the gardener to arrange the flowerpots.
Use the Pythagorean Theorem:
A²+B²=C²
6²+5²=C²
36+25=C²
61=C²
√61=C
So the answer is C.
