$\\ \rm\dashrightarrow10\sqrt{3x}+4\sqrt{3x}+5\sqrt{3x}+9\sqrt{3x}+9\sqrt{6x}+19\sqrt{3x}+19\sqrt{9x^3}$

$\\ \rm\dashrightarrow (10+4+5+9+19)\sqrt{3x}+9\sqrt{6x}+19\sqrt{3^2x^2x}$

$\\ \rm\dashrightarrow 47\sqrt{3x}+9\sqrt{2x}\sqrt{3x}+57x\sqrt{x}$

$\\ \rm\dashrightarrow (47+9\sqrt{2x})\sqrt{3x}+57x\sqrt{x}$

Answer:

$19\sqrt{3x}$

Step-by-step explanation:

Given expression:

$10 \sqrt{3x}+4\sqrt{3x}+5\sqrt{3x}$

Given answer options:

$9\sqrt{3x}$

$9\sqrt{6x}$

$19\sqrt{3x}$

$19\sqrt{9x^3}$

To simplify the given expression, factor out $\sqrt{3x}$ :

$\implies 10 \sqrt{3x}+4\sqrt{3x}+5\sqrt{3x}$

$\implies \sqrt{3x}(10+4+5)$

Add the numbers in the parentheses:

$\implies \sqrt{3x}(19)$

Rearrange to standard form:

$\implies 19\sqrt{3x}$

Therefore, the answer is the third option.

Find the equation of the line that passes through the points : (4 , -1 ) and (0 , -3)

Sergio [31]

Answer:

B. y= 1/2 x - 3

Step-by-step explanation:

base equation: y= mx+ b

slope(m) equation: $\frac{y_{2}-y_{2} }{x_{2} -x_{1} }$

y2= -1 y1= -3

x2= 4 x1= 0

$\frac{-1 - (-3)}{4-0} =\frac{2}{4} = \frac{1}{2}$

y- intercept: -3

found by taking the y from (0,-3)

A rectangle field has an area of 300 square meters and a perimeter of 80 meters. what are the length and width of the field?

Yakvenalex [24]

By definition the area of a rectangle is:
A = w * l
The perimeter is:
P = 2w + 2l
Where,
w: width
l: long
Substituting values:
300 = w * l
80 = 2w + 2l
Solving the system of equations we have:
l = 30 m
w = 10 m
Answer:
The length and width of the field are:
l = 30 m
w = 10 m

If (7^0)^x = 1, what are the possible values of x? Explain your answer.

kobusy [5.1K]

Hello,

What do you think of $7^0$ ?

It is 1

and what do you think of $1^x$ ?

it is 1

and the solution of 1 = 1 ?

There is an infinity of solutions as 1 = 1 is always true.

thanks
