The area of a rectangle is 45 cm2. Two squares are constructed such that two adjacent sides of the rectangle are each also the s

lorasvet [3.4K]

Answer:

The length of sides of one square is 5cm and length of sides of another square is 9cm

Step-by-step explanation:

Let the length of rectangle be x and width of rectangle be y.

We have given,

Area of rectangle = 45 cm²

i.e. Area of rectangle = x·y = 45 or xy = 45 ---------(1)

Next, two squares are constructed from two adjacent sides of rectangle.

i.e Side length of one square will be x and side length of another square will be y.

Area of one square = x²

And area of another square = y²

According to problem,

Sum of area of two squares is 106 cm²

∴ x²+y² = 106 ---------------(2)

From equation (1) and (2) , we can find x and y.

xy = 45 or x = $\frac{45}{y}$ , Plug this in equation (2).

We get,

x² + y² = 106

or $(\frac{45}{y} )^{2} + y^{2} =106$

or $\frac{45^{2} +y^{4} }{y^{2} } =106$

or $45^{2} + y^{4} = 106y^{2}$

On solving this equation we get ,

y²=81 or 25

or y = 9 or 5

for y =9 , x= $\frac{45}{9} =5$

or for y = 5 , x = $\frac{45}{5} =9$

Hence the length of sides of one square is 5cm and length of sides of another square is 9cm

Rewrite in simplest terms: -10(-v+6w)-w-9(-3w-v)−10(−v+6w)−w−9(−3w−v)

spayn [35]

The simplest form of the expression is -10 + 8v + 32w

Given the expression

-10(-v+6w)-w-9(-3w-v)

First, we need to expand the given equation using the distributive law:

-10(-v+6w)-w-9(-3w-v)

= -10-v+6w-w-9(-3w)+9(v)

= -10-v+6w-w+27w+9v

Collect the like terms:

= -10 - v +9v + 6w - w+ 27w

= -10 + 8v + 32w

Hence the simplest form of the expression is -10 + 8v + 32w

Answer:

Notebooks: $2.75 each; pens: $1.10 each

Step-by-step explanation:

Let n and p represent the unit cost of notebooks and the unit cost of pens.

Then 3n + 2p = $10.45, and 4n + 6p = $17.60.

Let's use elimination by addition/subtraction to find n and p.

Multiplying the first equation by -3, we get -9n - 6p = -$31.35

and then combine this with the second: 4n + 6p = $17.60

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

Then, -5n = -$13.75

Dividing both sides by 55, we get n = $13.75 / 5, so we now know that n = $2.75. Each notebook costs $2.75.

Subbing $2.75 for n in the first equation, we get:

3($2.75) + 2p = $10.45, or

$8.25 + 2p = $10.45

Solving for p, we get p = $2.20 / 2 = $1.10.

Each pen costs $1.10.
