Answer:

$x=-2$

Step-by-step explanation:

The given expression is

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

We group the constant terms on the right hand side to obtain;

$\sqrt{x+3}=5-4$

$\Rightarrow \sqrt{x+3}=1$

We square both sides of the equation to remove the square root.

$\Rightarrow (\sqrt{x+3})^2=1^2$

$x+3=1$

This will simplify to;

$x=1-3$

$x=-2$

Solve the equation. Identify any extraneous solutions

Lelu [443]

Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.

w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.

What is n-9 divided by 10=-2

DerKrebs [107]

The value of n is 11.

<u>Step-by-step explanation</u>:

The given expression is (n-9) ÷ 10 = -2

<u>To find the value of n</u> :

From the expression, it is determined that (n-9) is the numerator and 10 is the denominator.
Cross multiply the denominator in the left side of the expression to the another side.

The expression becomes (n-9) = (10 $\times$ -2).

⇒ n-9 = -20

Keep the n term on one side and the constants on other side.

⇒ n = -20+9

⇒ n = -11

Therefore, the value of n is 11.
