Answer:
see explanation
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16
= ( 4
)² ⇒ a = 4
1 = 1² ⇒ b = 1
Hence
16 - 1
= (4 )² - 1²
= (4 - 1)(4 + 1)
4 - 1 ← is also a difference of squares and factors as
(2x² - 1)(2x² + 1)
Thus
16 - 1
= (2x² - 1)(2x² + 1)(4 + 1 )
Answer:
$1191.60
Step-by-step explanation:
<u>Option 1:</u>
Leather Loveseat
1200 plus 2% extra charge and NO TAX
What is 2% of 1200??
0.02 * 1200 = 24
So total price = 1200 + 24 = $1224
<u>Option 2:</u>
Lush Blue Loveseat and Lamp
Lush Blue loveseat is 980 + 17% tax, that would be worth 980 + (0.17)(980) = $1146.6
and
lamp is worth 40 with 12.5% tax, that would be worth 40 + (0.125)(40) = $45
Total cost = 1146.6 + 45 = $1191.6
2nd option is cheaper, so that would cost $1191.60
True
merry Christmas and a happy new year :)
Answer: 40
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let:
We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2
Now subtract (2) from 2*(1) in order to eliminate x:
Solving for y:
Multiplying both sides by -1
Finally, replacing the value of y in (1)
Solving for x:
add 41 to both sides:
Multiply both sides by 1/2:
