Step-by-step explanation:
2(2+20)=80
4+40=80 (Distribute)
4+40-40=80-40(Subtract from both sides of the equation)
4=40(Simplify)
4/4=404/4(Divide both sides of the equation by the same term to get x=10)
=10
(√5 + 3)² / √20=
((√5 + 3)² / √20)(√20/√20)=
(√20(√5 + 3)²) / (√20)²=
√20(5+6√5+9) /20=
√20 (14+6√5) /20=
(14√20 +6√100) /20=
(14√20 +60) / 20=
(14(√4√5) + 60) /20=
(14(2)(√5)+60) / 20=
(28√5+60) /20=
(7√5+15) / 5
Answer:(√5 + 3)² / √20= <span>(7√5+15) / 5</span>
Answer:
12
Step-by-step explanation:
AD is 6. a bisector splits a line in half. X would equal 6 meaning AD would equal 12.
