What is the simplified form of the expression 11[(9^2-5^2) divided by 2^2+8]
224.5
242
51.3
110

51.3

Step-by-step explanation:

In order to calculate this, you have to remember the norms for the solution of math problems with hierarchy of operations called PEMDAS:

   Parentheses (simplify inside 'em)

   Exponents

   Multiplication and Division (from left to right)

   Addition and Subtraction (from left to right)

So we first solve parentheses:

11[(9^2-5^2)= 11(81-25)=11(56)= 616.

and now we have to divide that by the result of:

2^2+8

Remember first exponents:

2^2+8= 4+8=12

ANd now we just divide:

616/12=51.3333

So the answer would be 51.3

answer: i don't understand it

step-by-step explanation: sorry

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
