Question

(1/2)(9.1- 5)2 + 5(7.2 + 2)2

Answer 1

(1/2)(9.1 - 5)2 + 5(7.2 + 2)2

1/2 times 4.1 times 2 + 5(7.2 + 2) times 2

1/2 times 4.1 times 2 + 5 times 9.2 times 2

4.1 + 5 times 9.2 times 2

4.1 + 46 times 2

4.1 + 92

96.1 is the answer

Hope this helps!

Answer 2

We are given the following expression:

`\mleft((1)/(2)\mright)\mleft(9.1-5\mright)^2+5\mleft(7.2+2\mright)^2`

To simplify this expression we will first add the terms inside the parenthesis:

`(1)/(2)(14.1)^2+5(9.2)^2`

Now, we will solve the exponents:

`(1)/(2)(198.81)+5(84.64)`

Now we solve the products:

`99.41+423.2`

Now we solve the addition:

`522.61`

therefore, the expression reduced to 522.61
