The dimensions of a rectangle are 2x - 5 and 2x - 5. Which expression represents the area of the rectangle in simplest terms?

Answers

Answer 1

Answer:

Step-by-step explanation:

(a - b)² = a² - 2ab +b²

Area of rectangle = length * width

                             = (2x - 5)(2x -5)

                             = (2x - 5)²

                            = (2x)² - 2*(2x)(5) + 5²

                             = 4x² - 20x + 25

Larrie and Lester went shopping. They both went with equal amount of money. Larrie spent $120.00 and Lester spent $150.00. At the end of the shopping Lester had 2/3 of what Larrie had left. How much mone did Latrine have after shopping?

Answers

Answer:

$90.00

Step-by-step explanation:

Larrie and Lester went shopping. They both went with equal amount of money.

Let initial amount = x

Larrie = Lester = x

Larrie spent $120.00 and Lester spent $150.00.

Amount left (Larrie) = x - $120.00

Amount left (Lester) = x - $150.00

At the end of the shopping Lester had 2/3 of what Larrie had left.

Amount left (Lester) = 2 / 3 (Amount left (Larrie)

x - 150 = 2/3 (x - 120)

solving for x;

3 (x - 150) = 2 (x - 120)

3x - 450 = 2x - 240

3x - 2x = -240 + 450

x = 210

How much money did Latrine have after shopping?

Amount left (Larrie) = x - $120.00

Amount left (Larrie) = $210.00 - $120.00

Amount left (Larrie) = $90.00

A swimming pool holds 18,000 gallons of water. The pool is 40% full. How many more gallons are needed to fill the pool?

Answers

Answer:

Since 40% of 18,000 gallons is 7,200 gallons filled up, then 18,000-7,200 gallons= 10,800 gallons left to fill up the pool

Step-by-step explanation:

40% of 18,000 gallons means

40 x 180= 7,200 gallons

18,000-7,200 gallons= 10,800 gallons

There were 203 tickets sold for a wrestling
match. For activity card holders the price was
$1.25 and for non-card holders the price was
$2.00. The total amount of money collected was
$310. How many of each type of tickets were
sold?

Answers

Answer:

the number of activity card holders is 128 and non-card holders is 75 respectively

Step-by-step explanation:

Let us assume the activity card holders be x

And, the non-card holders be y

Now as per the given situation

x + y = 203

x = 203 - y

1.25x + 2y = 310

Now put the value of x in the above equation

1.25(203 - y) + 2y = 310

253.75 - 1.25y + 2y = 310

0.75y = 56.25

y = 75

And,

x = 203 - 75

= 128

Hence, the number of activity card holders is 128 and non-card holders is 75 respectively

A rectangular window is 4x inches wide and 8x inches long. What is an expression for the distance from one corner of the window to the opposite

Answers

Answer:

Step-by-step explanation:

Pythagorean theorem

a² + b² = c²          a = 4x     b=8x

c = √(a² + b²)

c =√((4x)² + (8x)²)

  = √(16x² + 64x²)

  = √80x²

  = √(16×5)x²
