The combined area of a pair of congruent rectangles can be represented, in square units, by the expression 18y^2-818y 2 −8. The

sveta [45]

Answer:

$Perimeter = 12y$

Step-by-step explanation:

Given

$Area = 18y^2 - 8$ -- two rectangles

Required

Determine the perimeter of one of the rectangles

First, calculate the area (A) of 1 rectangle

$A =\frac{1}{2}Area$

$A =\frac{1}{2}(18y^2 - 8)$

$A =9y^2 - 4$

Express as difference of two squares

$A =(3y - 2)(3y+2)$

Area is calculated as:

$A = Length * Width$

So, by comparison:

$Length = 3y - 2$

$Width = 3y + 2$

The perimeter is:

$Perimeter = 2 *(Length + Width)$

$Perimeter = 2 *(3y-2+3y+2)$

Collect Like Terms

$Perimeter = 2 *(3y+3y-2+2)$

$Perimeter = 2 *(6y)$

$Perimeter = 12y$

A man has 33 coins in his pocket, all of which are dimes and quarters. If the total value of his change

kupik [55]

Answer:

Number of dimes = 16

Number of quarters = 17

====================================================

Work Shown:

d = number of dimes

q = number of quarters

d+q = 33 coins total, this solves to d = 33-q

10d = value of all the dimes in cents

25q = value of all the quarters in cents

10d+25q = 585 cents total

--------------

Plug in d = 33-q and solve for q

10d+25q = 585

10(33-q) + 25q = 585

330-10q+25q = 585

15q+330 = 585

15q = 585-330

15q = 255

q = 255/15

q = 17

The man has 17 quarters

d = 33-q = 33-17 = 16

He also has 16 dimes.

--------------

Check:

16 dimes + 17 quarters = 33 coins total

16 dimes = 16*10 = 160 cents

17 quarters = 17*25 = 425 cents

160 cents + 425 cents = 585 cents

The answer is confirmed.
