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
Perform the operations inside parenthesis first:
Perform the square:
Perform the product:
Perform the sum:
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:
simply draw the same coordinates sideways at a 180 angle
Step-by-step explanation:
The answer is: 1 + 5a ; or, 5a + 1 .
______________________________
Given the expression:
______________________________
<span>1 + 10a − 5a ;
________________
→ We identify the "like terms" ;
___________________________
→ which are "10a" and ( "-5a") ;
____________________________
→ 10a </span>− 5a = 5a ;
_________________________________
→ 1 + 5a ; is the most simplified; or write the expression as: 5a +1 .
