57.4 because u add all the side up and u get a answer
Lets consider the side of square be 'x' units
So as per data,
Length of rectangle is x+5
Breadth of rectangle is x/2
and also as per data, the areas of rectangle and square are equal.
Area of rectangle = Length * Breadth = (x+5)*x/2 =

<- equation1
Area of square = Side* Side= x*x =

<- equation2
As per given data, Equation1 and equation 2 are equal
so

= tex] x^{2} [/tex]



x = 5
So the side of square = 5 units
For Square, both dimensions are equal.
Answer:
z = - 1
Step-by-step explanation:
z + (z - 6) - 2 = - 10 ← remove the parenthesis on left side
z + z - 6 - 2 = - 10 , that is
2z - 8 = - 10 ( add 8 to both sides )
2z = - 2 ( divide both sides by 2 )
z = - 1
Answer:
all you have to do is look up your question in you will find it
Answer:
- 9 nickels
- 12 dimes
- 6 quarters
Step-by-step explanation:
We are given relations between the number of each kind of coin and the number of quarters. So, it is convenient to write an equation in terms of the number of quarters.
Let q represent the number of quarters. The number of nickels is 3 more than that, so is (q+3). The number of dimes is 6 more than the number of quarters, so is (q+6). The total value of the coins, in cents, is ...
5(q +3) +10(q +6) +25q = 315
40q +75 = 315 . . . . . . . . . . . . . . collect terms
40q = 240 . . . . . . . . . subtract 75
q = 6 . . . . . . . . . divide by 40
q +3 = 9 . . . . number of nickels
q +6 = 12 . . . number of dimes
There are 9 nickels, 12 dimes, and 6 quarters in the collection.
