Answer:
x²^2 + 4x + 4 - 9y²=(x+2-3y) (x+2-3y)
Step-by-step explanation:
hello :
x²+4x+4 = x²+2(2x)+2²=(x+2)² use identity : (a+b)² = a²+2ab+b²
( x² + 4x + 4) - 9y² = (x+2)²-(3y)² = (x+2-3y) (x+2-3y) use identity :
a²-b² =(a-b)(a+b)
Answer:
$2,407.5
Step-by-step explanation:
To solve this question, we will use the formula for calculating the amount formula as shown;
A =P(1+r)^n
Given that;
P = #$1300
r = 4.5% = 0.045
t = 14years
Substitute
A = 1300(1+0.045)^14
A = 1300(1.045)^14
A = 1300(1.8519)
A = 2,407.5
Hence Isabella would have $2,407.5 in her account after 14years

Step-by-step explanation:
Answer:
For 2 hours of dog stinting the total cost will be the same for the two services.
Step-by-step explanation:
x to represent the number of hours of dog sitting
<u>Derrick's Dog Sitting </u>
Fixed charged rates = $12
Sitting charges per hour = $7
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $7) = 7x
⇒Total charges of Derrick's Dog Sitting for x hours = Fixed charge + Hourly Rate
= $7x + 12
<u> Darlene's Dog Sitting</u>
Fixed charged rates = $16
Sitting charges per hour = $5
⇒Charges for x hours siting = x ( Charges per hour)
= x ( $5) = 5x
⇒Total charges of Darlene's Dog Sitting<u> </u>for x hours = Fixed charge + Hourly Rate
= $5x + 16
Now, according to the question:
for x hours sitting, both company charges are same.
⇒ $7x + 12 = $5x + 16
or, 7x - 5x = 16 - 12
or, 2x = 4
⇒ x = 2
Hence, for 2 hours of dog stinting the total cost will be the same for the two services.
