PLEASE HELP ME NOW!!
puteri [66]

Answer:

x=4+-2\sqrt{7}

Step-by-step explanation:

To solve, we need to take square root of both sides first:

(x-4)^2=28\\\sqrt{(x-4)^2} =+-\sqrt{28} \\x-4=+-\sqrt{28}

Now we use the property of radical shown below to simplify square root of 28:

Property:  \sqrt{x*y}=\sqrt{x} \sqrt{y}

Now, we have:

x-4=+-\sqrt{28}\\x-4=+-\sqrt{4*7}\\x-4=+-\sqrt{4}\sqrt{7}\\x-4=+-2\sqrt{7}

Now we take 4 to the other side and isolate x:

x-4=+-2\sqrt{7} \\x=4+-2\sqrt{7}

first answer choice is right.

2.<br>Remove the brackets and simplify <br>a) (x + 1) + (x + 2)?​
devlian [24]

Step-by-step explanation:

✲ \text{(x + 1) + (x + 2)}

Remove the unnecessary brackets :

⇢ \text{x + 1 + x + 2}

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⇢ \text{x + x + 1 + 2}

⇢ \text{2x + 3}

\red{ \boxed{ \boxed{ \text{Our \: final \: answer :  \boxed{ \underline{  \tt{2x + 3}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
