Cari simplifies the expression (5 + 4) 2− 5 × 2. Part A Cari shows her work on the board. Use numbers and words to explain her mistake. (5 + 4) 2− 5 × 2 (5 + 16) − 5 × 2 21 − 5 × 2 16 × 2 32

Please see explanation for answer.

Step-by-step explanation:

Simplifying the expression

5 + 4) 2− 5 × 2

Carl's method

(5 + 4) 2− 5 × 2 first error was taking only 4 from the bracket and squaring it.

Instead of solving the bracket as a whole before solving outside. And once she got it wrong from the start, every other solving would be wrong

(5 + 16) − 5 × 2

21 − 5 × 2

16 × 2

32

The right method

In simplifying the expression, we must bring in Mind our Bodmas

Which means we tackle Brackets before division, then multiplication , then addition and lastly subtraction.

(5 + 4) 2− 5 × 2

Solving the bracket first we have

(9)2-5x2

Since there is no division, we move to multiplication and we can see two sites for multiplication(9 x 2 and 5x2)

18-10

Subtracting will give us 8 as our answer.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
