Answer:
1)
2)
3)
Step-by-step explanation:
So we know that the perimeter of the rectangle is 50.
The formula for the perimeter of a rectangle is given by:
Where l is the length and w is the width.
The length is (x+5) and the width is (x).
Thus, substitute (x+5) for l and (x) for w. Also substitute 50 for P. Therefore:
And that's our equation.
To solve, first distribute:
Combine like terms:
Subtract 10 from both sides:
Divide everything by 4:
So, the value of x is 10.
The length is the longer side. Thus, it is (x+5).
We now know that x is 10, substitute:
So, the length is 15 units.
For the answer to A would be 2d+ 205
Answer:a
Step-by-step explanation: it follows a proportional rate since on the y it goes up by 5 and on the x it goes by 1
