Answer:
The answer to your question is:
x = 1
Square's perimeter = 12
Rectangle perimeter = 12
The value of x is one and the perimeter of the square and the rectangle is the same.
Step-by-step explanation:
Data
Side of Square = 4x - 1
Length of rectangle = 2x + 1
Width = x + 2
Perimeters are the same
Process
Square perimeter = 4(4x - 1)
Rectangle's perimeter = 2(2x + 1) + 2(x+ 2)
Then
4(4x - 1) = 2(2x + 1) + 2(x+ 2) Equation
16x - 4 = 4x + 2 + 2x + 4
16x - 4 = 6x + 6
16x - 6x = 6 + 4
10x = 10
x = 10 / 10
x = 1
Perimeter of the square = 4(4(1) - 1)
= 4(3)
= 12
Perimeter of the rectangle = 2(2(1) + 1) + 2((1)+ 2)
= 2(3) + 2(3)
= 6 + 6
= 12
Hi there!
nickels:19
We know that there is only nickels and dimes in his coin collection..
<u><em>1.Multiply two terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>
<u><em>2.Multiply the terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>3.Combine the two terms:</em></u>
<u><em /></u>
<u><em /></u>
Therefore, there would be 19 nickels...

S=saving
X=amount left
S-55=x
Another way : x=s-55
