you are kidding?
put this into your google search engine:
20 +(17.5-6.5)^2 =
PEMDAS
first solve in the parentheses: (17.5-6.5)
then square the difference
finally add 20
To work out the expression 20 + (17.5 - 6.5) squared, we need to follow the order of operations, which is also known as BIDMAS (Brackets, Indices, Division/Multiplication, Addition/Subtraction):
Step 1: Calculate the expression inside the brackets.
17.5 - 6.5 = 11
Step 2: Square the result from Step 1.
11 squared = 11^2 = 121
Step 3: Add the result from Step 2 to 20.
20 + 121 = 141
Therefore, the answer to 20 + (17.5 - 6.5) squared is 141.
To work out 20 + (17.5 - 6.5) squared, you can follow these steps:
Step 1: Start by calculating the expression inside the parentheses, (17.5 - 6.5).
- Subtract 6.5 from 17.5: 17.5 - 6.5 = 11
Step 2: Square the result from Step 1.
- To square a number, you multiply it by itself: 11 * 11 = 121
Step 3: Add the result from Step 2 to 20.
- Add 121 to 20: 121 + 20 = 141
So, 20 + (17.5 - 6.5) squared equals 141.
