Evaluate this expression for x =5

6+(10-x)^2-20

Answer

61

Step-by-step explanation:

6+(10-x)^2-20 x=5

6+10^2-x^2-20

6+100-x^2-20

106-20-x^2

86-(5)^2 ( because the question said x is 5)

86-25

61

11

Step-by-step explanation:

For problems like this try using PEMDAS. PEMDAS is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. First you want to solve what is inside parentheses and distribute the 5 in for x. You'd subtract 10-5 now you have 6+5^2-20. Then you do your exponents and 2 is your only exponent. So that'd be 5 to the 2nd power which is 25. So now you have 6+25-20. There is no multiplication or division so you'd skip it so next you go on to addition. Which is 6+25 to get 31 and now you have 31-20. Last you subtract those and get 11.

what shape is

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
