Quiz<br> 6. Simplify the expression.<br> 4 (10 – 4)² + 4)<br> A6<br> B 36<br> D 12
larisa86 [58]

This is all about operations priority! We have to perform the operations in the right order, remembering that parentheses come first, then powers, then multiplications and then additions:

Start with

4(10-4)^2+4

Perform the operations inside parenthesis first:

4\cdot 6^2+4

Perform the square:

4\cdot 36+4

Perform the product:

144+4

Perform the sum:

148

Note: you have an extra parenthesis at the end, and none of the options meets the result. I'm afraid that there's a typo in the question, but this should still give you a valid strategy to solve the actual exercise.

Answer:

24!

Step-by-step explanation:

I will refer the people to A,B,C, and D

24 is the answer.

4 choices for the first position.

3 choices for the second.

2 choices for the third.

1 for the fourth.

4*3*2*1=24

Here it is listed out where a,b,c,d are the 4 people:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bcda

bdac

bdca

cabd

cadb

cbad

cbda

cdab

cdba

dabc

dacb

dbac

dbca

dcab

dcba

(of course, this assumes that there is a direction to the line, or a 'front' and a 'back'.  If direction doesn't matter then the answer is 12, since every combination above has a reverse.  e.g., abcd and dcba.  The list becomes:

abcd

abdc

acbd

acdb

adbc

adcb

bacd

badc

bcad

bdac

cabd

cbad
