Answer:

Step-by-step explanation:

(10x + 15y)² = (8x + 12y)² + (6x + 9y)²

{(a + b)² = a²+2ab + b² }

(10x)² + 2*10x*15y + (15y)² = (8x)² + 2*8x*12y + (12y)² + (6x)² + 2*6x*9y +(9y)²

100x² +300xy + 225y² = 64x² + 192xy + 144y² + 36x² + 108xy + 81y²

100x² +300xy + 225y² = 100x² + 300xy + 225

Answer:

b. $\displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2$

a. $\displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2$

Step-by-step explanation:

b. $\displaystyle 225y^2 + 150xy + 100x^2 = 225y^2 + 150xy + 100x^2$

a. $\displaystyle [8x + 12y]^2 + [6x + 9y]^2 = [10x + 15y]^2$

The two expressions are identical on each side of the equivalence symbol, therefore they are an identity.

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p - 24.1t+575 where t is

krok68 [10]

Answer:

69 years after 2005 which is in 2074 year the average price of a studio in this city will reach $1081.10.

Step-by-step explanation:

Given:

Average Price to rent a studio is denoted by 'p'.

It is been approximated by equation:

$p-24.1t+575$

where t ⇒ number of years since 2005

Now given:

Average Price to rent a studio p = $1081.10

Substituting the value of p in above equation we get;

$1081.10-24.1t+575$

Solving the new equation to find the value of t we get;

$1656.1=24.1t$

Dividing both side by 24.1 we get;

$\frac{1651.1}{24.1} =\frac{24.1t}{24.1} \\\\t= 68.71 \approx 69 years$

Hence 69 years after 2005 which is in 2074 year the average price of a studio in this city will reach $1081.10.
