Answer:
Step-by-step explanation:
First of all let's notice that 
while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of 
it means tha 
is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)
At this point 2 is a zero, and our final factoring is a
Let's take an mathematical example
Let's find the ratio of volume of a cone and cylinder if radius and height are same for both .
See
- V for cone=1/3πr²h
- V for cylinder=πr²h
The ratio is 1:3
Step-by-step explanation:
5p=12h
3p=?(h)
12×3=5h
36=5h
h=36/5
h=7.2 hours
Answer:
809.4cm²
Step-by-step explanation:
Given the following :
Systematic error = 3.8cm (The measured length is always more than the actual length.)
Most probable dimension :
Width = 85.7 cm
Length = 123.5 cm
Hence most probable area of Rectangle :
Area = Length × Width
Area = 85.7cm × 123.5cm = 10583.95 cm²
Dimension due to Systematic error :
Length = (85.7cm + 3.8cm) = 89.5cm
Width = (123.5cm + 3.8cm) = 127.3cm
Area = Length × width
Area = ( 89.5cm × 127.3) = 11393.35cm²
Systematic error of the area :
value of area with Systematic error - Probable value of area :
11393.35cm² - 10583.95 cm² = 809.4cm²
