1) Simplify : - 4x + 3(2x + 5) - 3x + 12
breaking 3(2x + 5) we get,
Now, as per the PEMDAS rule let's shorten the like terms
<u>Correct option is C i.e. - x + 27</u>
2) Simplify : 3x + 3(x + 6) - 4 - 5x
breaking 3(x + 6) we get,
Again using the same rule we see,
<u>Correct answer is option C i.e. x + 14</u>
3) Expression : y[x² - 2(1 + 2)] ÷ y + 5²
In this case we are given that <em>x = 3</em> whereas <em>y = 7</em>
Putting the values of x and y we see,
<u>Henceforth, the final answer is 28</u>
Answer:
It would be 1
Step-by-step explanation:
The equation is ( 6-2) divided by ( 3 +1)
Using GEMDAS we do the groups first so
6 - 2 = 4
3 + 1 = 4
Divide 4 by 4 and the answer is 1
The equivalent expressions are 6y + 4 and 11y + 16
<h3>How to determine the equivalent expressions?</h3>
<u>Expression (A)</u>
We have:
2y + 4(y + 1)
Open the bracket
2y + 4y + 4
Evaluate the like terms
6y + 4
<u>Expression (B)</u>
We have:
9y + 6 + 2(5 + y)
Open the bracket
9y + 6 + 10 + 2y
Evaluate the like terms
11y + 16
Hence, the equivalent expressions are 6y + 4 and 11y + 16
