\bf \sqrt{18x^7}\qquad 
\begin{cases}
18\\
\qquad 2\cdot 3\cdot 3\\
\qquad 2\cdot 3^2\\
x^7\\
\qquad  x^{2+2+2+1}\\
\qquad x^2\cdot x^2\cdot x^2\cdot x^1\\
\qquad (x^2)^3x^1\\
\qquad (x^3)^2x^1
\end{cases}\implies \sqrt{2\cdot 3^2\cdot (x^3)^2\cdot x}
\\\\\\
3\cdot x^3\sqrt{2\cdot x}\implies 3x^3\sqrt{2x}

Andy joins a social networking site. After day three, he has 25 friends; after day eight, he has 40 friends. Write the equation
Allisa [31]

Answer:

Point slope intercept form: The equation for line is given by; y-y_1=m(x-x_1) ......[1] ; where m is the slope and a point (x_1, y_1) on the line.

Let x represents the number of days and y represents the number of friends.

As per the statement:  After day three, he has 25 friends; after day eight, he has 40 friends.

⇒ We have two points i.e,

(3, 25) and (8, 40)

First calculate slope(m);

m = \frac{y_2-y_1}{x_2-x_1}

Substitute the given values we get;

m = \frac{40-25}{8-3}=\frac{15}{5} = 3

now, substitute the given values of m=3 and a point (3, 25) in [1] we get;

y-25=3(x-3)

Using distributive property; a \cdot(b+c) = a\cdot b + a\cdot c

y-25 = 3x - 9

Add 25 on both sides, we get;

y-25+25 = 3x - 9+25

Simplify:

y =3x + 16

if  x = 18 days, then;

y = 3(18) + 16 = 54+16 = 70

Therefore, he will have on day 18, if he continues to add the same number of friends each day is, 70 friends.
