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.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
