<span>when comparing fractions we need to bring the fractions to the same denominator
to compare and see which is bigger or smaller.
the denominators of the 3/4 and 11/16 are 4 and 16 respectively.
we can mulitply both numerator and denominator of 3/4 by 4 so that the denominator is now 16,
then the fraction </span>
<span>
now we can compare the 2 fractions 12/16 and 11/16,
when denominator is same then bigger numerator is the bigger fraction. therefore 3/4 is the greater fraction </span>
For every single cat there is four dogs
18 + 81 = 9(x²<span> + 6x + 9)
</span><span>11 = (x + 3)</span>²
When we are completing the square, we are going to move the value of c across the equals. We will do that by adding, and end up with
18=9(x²+6x)
We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9
This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)
Dividing both sides by 9, we have:
11=x²+6x+9
11=(x+3)²
Answer:
<em>122.46 cm² </em>
Step-by-step explanation:
A =
~~~~~~~~~
= 8 cm
= 5 cm
A = 3.14 ( 8² - 5² ) ≈ <em>122.46 cm²</em>
