Answer: Factors are (5x+1)²

Step-by-step explanation:

Given expression : $25x^{2} + 10x+ 1$

We have to find the factors of the above expression

In order to find the factors of a quadratic equation we multiply the first term with the third term

i.e. $25x^{2} \times1$

= $25x^{2}$

Now to break it in multiples such that their sum or difference is equal to the middle term

If we take (5+5)x that makes 10x

$25x^{2} + 5x +5x+1$

5x(5x+1) +1(5x+1)

=(5x+1)(5x+1)

or (5x+1)²

Answer:

The value of x is 7.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denormintor the same and make it into simplest form :

$\frac{x}{3} + \frac{x}{6}$

$= \frac{x \times 2}{3 \times 2} + \frac{x}{6}$

$= \frac{2x}{6} + \frac{x}{6}$

$= \frac{2x + x}{6}$

$= \frac{3x}{6}$

$= \frac{x}{2}$

Next you have to multiply both sides by 2 in order to make x the subject :

$\frac{x}{2} = \frac{7}{2}$

$\frac{x}{2} \times 2 = \frac{7}{2} \times 2$

$x = 7$

it looks as though you made 72 of your goal so far for the month you only have 5 days left to reach 100% of your goal let me rem

dezoksy [38]

72% can also be written as 0.72, so take 0.72 x 45 = 32.4

Subtract 32.4 from 45 45 - 32.4 = 12.6 You need 12.6 renewals in 5 days.
