Step-by-step explanation:

First find the area of the rectangle with the variables.

$(x + 5) \times x = {x}^{2} + 5x$

Now the areas are equal, so we have to solve the equation

${x}^{2} + 5x = 36 \\ x + \sqrt{5x} = 6 \\ 3.236x = 6 \\ x = 1.854$

Three multiplied by the sum of 4 and a number is the same as 18 more than the number. Find the number.

arsen [322]

3(4+n)=18+n
distribute
12+3n=18+n
minus n both sides
12+2n=18
minus 12 both sides
2n=6
divide by 2
n=3

the number is 3
equation is
3(4+n)=18+n

Which expression is equivalent to this expression? x(2x+3) Question 1 options: 2x2+3 2x2+3x 2x2−3x 3x + 3

sleet_krkn [62]

Answer:

$2x^2+3x$ is the expression which is equivalent to $x\left(2x+3\right)$ .

In other words:

$x\left(2x+3\right)=2x^2+3x$

Step-by-step explanation:

Given the expression

$x\left(2x+3\right)$

solving

$x\left(2x+3\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$a=x,\:b=2x,\:c=3$

$=x\cdot \:2x+x\cdot \:3$

$=2xx+3x$

$=2x^2+3x$ ∴ $2xx=2x^2$

Thus,

$x\left(2x+3\right)=2x^2+3x$

Therefore, $2x^2+3x$ is the expression which is equivalent to $x\left(2x+3\right)$ .
