Answer:
5.236
Step-by-step explanation:
Take the square root of 5 to get rid of the ^2
You are left with 
Answer:
x=4
Step-by-step explanation:
Add 99 to both sides.
-4(x+5)=-45+9−4(x+5)=−45+9
Simplify -45+9−45+9 to -36−36.
-4(x+5)=-36−4(x+5)=−36
Divide both sides by -4−4.
x+5=\frac{-36}{-4}x+5=
−4
−36
Two negatives make a positive.
x+5=\frac{36}{4}x+5=
4
36
Simplify \frac{36}{4}
4
36
to 99.
x+5=9x+5=9
Subtract 55 from both sides.
x=9-5x=9−5
Simplify 9-59−5 to 44.
x=4
1 + 2V3+3
-2
4 + 2V3
-2
dividing each term by -2 as a final step,
=-2 - V3
