Answer:
Question 8: 8.94
Question 9: 8.94
Step-by-step explanation:
Question 8: Using pythagorean theorem [a^2+b^2=c^2], we do (8*8)+(4*4) getting 80 which is our c^2. Now we find the square root of which is 8.94.
Question 9: Using pythagorean theorem [a^2+b^2=c^2], we do (5.3*5.3)+(7.2*7.2) getting 79.93 which is our c^2. Now we find the square root of which is 8.94.
Please correct or msg me if this is wrong.

Answer:
yes
Step-by-step explanation:
To avoid confusion, remember PEMDAS. This is the order of operation.
Parenthesis, Exponents, Multiply, Divide, Add, Subtract
21 ÷ 7 + 20 * 102 * 2 - 3
No parenthesis and no exponents, proceed to multiplication.
20 * 102 * 2 = 4,080
Then, perform division
21÷7 = 3
Then, do addition
3 + 4080 = 4083
Lastly, do subtraction
4,083 - 3 = 4,080
So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
THEREFORE THE ANSWER IS 4,080
