Solve the radical equation. square root 6n-11= n – 3 Which solution is extraneous? A.)2

Anvisha [2.4K]

ANSWER

D) 10

EXPLANATION

We want to solve the radical equation,

$\sqrt{6n - 11} = n - 3$

Square both sides,

$6n - 11 = (n - 3) ^{2}$

Expand brackets on right hand side,

$6n - 11 = {n}^{2} - 6n + 9$

Rewrite in general quadratic equation form,

${n}^{2} - 12n + 20 = 0$

Factor to obtain,

$(n - 2)(n - 10) = 0$

Apply the zero product principle to get,

$n = 2 \: or \: n = 10$

We put n=2 into the equation to get,

$\sqrt{6(2) - 11} = 2 - 3$

$1 = - 1$

This statement is false, hence 2 is an extraneous solution

We put n=10, to get

$\sqrt{6(10) - 11} = 10 - 3$

$\sqrt{49} = 7$

$7 = 7$

This is true, hence the only solution is
$n = 10$

How to get 2 essays and pre-essay questions done in 238 minutes? (3 hours and 58 min) PLEASE HELP

Amanda [17]

Answer:

Definitely start with outlining one essay, then doing all of your steps, although don't do much re-writing since there may not be enough time. only focus on one at a time though. as for the questions, since it says pre-essay it wants that completed first but unless you have to do it first, i would do it last since the essays are more important.

There are 700 pupils in a school. The ratio of girls to boys is 3:4. How many girls are there?

Alexxandr [17]

Answer:

300

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 = 7 parts

Divide the total by 7 to find the value of one part of the ratio.

700 ÷ 7 = 100 ← value of 1 part of the ratio, thus

3 parts = 3 × 100 = 300 ← number of girls

4 parts = 4 × 100 = 400 ← number of boys
