if x.y is given

then it is equal to $=\frac{(x+y)\times x}{y-3}$

For 1st example

3.4 $=\frac{(3+4) \times 3}{4-3} =\frac{21}{1} =21$

For 2nd example

2.5 $=\frac{(2+5) \times 2}{5-3} =\frac{7 \times 2}{2} =7$

⇒4.4 $=\frac{(4+4)\times 4}{4-3} =32$

Which expression is the factorization of x2 + 10x + 212

Montano1993 [528]

Answer:

The answer is option 1.

Step-by-step explanation:

Firstly, you have to elaborate the expression :

${x}^{2} + 10x + 21$

$= {x}^{2} + 3x + 7x + 21$

Next you have to take out the common factors and factorize it :

${x}^{2} + 3x + 7x + 21$

$= x(x + 3) + 7(x + 3)$

$= (x + 7)(x + 3)$

Melania walked her dog 2 1/5 miles. Cathy walked her dog 1 3/4 times as far as Melania did. How many miles did Cathy walk her do

Step2247 [10]

Make the fractions improper to multiply.2 1/5 becomes 11/5 and 1 3/4 becomes 7/4. multiply the numerators then multiply the denominators. you get 77/20, which is simplest form. don't let teachers feed you that bs about it having to be a mixed number. an improper fraction is way more useful.
