Answer: 2(7x + 3y + 4) [unsimplified] or 14x + 6y + 8 [simplified]
Step-by-step explanation: The perimeter of a parallelogram is 2 * (the two sides.)
Adding 5x + 4 and 2x + 3y, we get 7x + 3y + 4 by combining like terms in the x terms.
Now, we multiply by 2. This is 2(7x + 3y + 4) or 14x + 6y + 8
Answer:
432
Step-by-step explanation:
Simple..
Number of children on Saturday= 37
Number of children on Sunday= 25
Now add 37+25 which is 62
There were 62 children on those 2 days
Hope This Helps!
First think out the equation, once you've done that multiply 3 by 25 to get 75
The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.
<h3>How to calculate the value?</h3>
From the information given, it should be noted that we simply want to calculate the value of x.
This will be:
18x + 9∆x - 7
It was stated that ∆x = 0
Therefore, we'll put this into the equation.
This will be:
18x + 9∆x - 7
= 18x + 9(0) - 7
= 18x -7
