Answer:

\large \boxed{\sf \  \  x^2 + 7x + 5 \ \ }

Step-by-step explanation:

\mathrm{\sf (-3x^2  + 2x -4) + (4x^2  + 5x + 9)}

Remove brackets.

\large{\sf -3x^2  + 2x -4 + 4x^2  + 5x + 9}

Group like terms.

\large{\sf -3x^2 + 4x^2 + 2x  + 5x + 9  -4}

Combine like terms.

\large{\sf x^2 + 7x + 5}

Proof true or false: For all integers a,b,and c,if ab|c then a|c and b|c
olya-2409 [2.1K]

Answer with explanation:

It is given that for three integers , a, b and c, if

              \frac{ab}{c}\rightarrow then, \frac{a}{c} \text{or} \frac{b}{c}

Since , a b is divisible by c , following are the possibilities

1.→ a and b are prime integers .Then , c will be prime number either equal to a or b.

2.→a and b are not prime integers ,then any of the factors of a or b will be equal to c.For example:

 ⇒a=m × n

 b=p × q× c

or,

⇒a=u×v×c

b=s×t

So, whatever the integral values taken by a, and b, if \frac{ab}{c} then either of  \frac{a}{c} \text{or} \frac{b}{c} is true.

Arrange the number in increasing order<br><br><br> 14.204 14.200 14.240 14.210
Gnesinka [82]

Answer:

14.200,14.204,14.210,14.240

Step-by-step explanation:

To arrange in increasing order, we start from the least number and end on the highest number.

The given numbers are,14.204, 14.200, 14.240, 14.210

We can observe that:

14.200<14.204<14.210<14.240

Therefore the numbers in increasing order is 14.200,14.204,14.210,14.240
