Answer:
20
Step-by-step explanation:
Remember PEMDAS!
So first parentheses:
1.6^2 = 2.56
8.7 + 9.3 = 18.
Because that is inside another parentheses you multipy them.
2.56 x 18 = 46.08
Now: 46.08 divided by 1.8 = 25.6
Now subtract:
25.6 - 3.7 - 1.9 which equals 20!

Answer:
x=i√33−3,−i√33−3
hope this helps :)
Step-by-step explanation:
Subtract 5 from both sides of the equation.
(x+3)2=−28−
5 Subtract 5 from −28.
(x+3)2=−33
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x+3=±√−33
Simplify the right side of the equation.
x+3=±i√33
The complete solution is the result of both the positive and negative portions of the solution.
x=i√33−3,− i√33 −3
