Since we want it in the form: (x - a)², let's first expand (x - a)² and then equate for the coefficients.
(x - a)² = x² - 2ax + a²
x² + 4x - 15 = x² - 2ax + a²
Now, let's focus on the middle term.
4x = -2ax
4 = -2a
a = -2
Thus, we know that a = -2
Then, we can say (x + 2)² = x² + 4x - 15
x² + 4x + 4 = x² + 4x - 15
Thus, 19 units are needed in order to complete the square to produce:
(x + 2)²
Lois is correct. This is because multiplication is repeated addition. It means that when your addends are just the same number but added several times, the sum is just equivalent to the product of that number times the number of times it was added. For example, 4+4+4 = 4×3 = 12.
Answer:
The correct answer is A.
Step-by-step explanation:
face value = 1.86 , charges are 20% more for smokers
⇒ Charges = 20% of 250000 = $50000
Total charge = Charge × face value
= 50000 × 1.86 = $93000
face value = 1.86 , charges are 18% more for smokers
⇒ Charges = 18% of 250000 = $45000
Total charge = Charge × face value
= 45000 × 1.86 = $83700
face value = 2.07 , charges are 25% more for smokers
⇒ Charges = 25% of 250000 = $62500
Total charge = Charge × face value
= 62500 × 2.07 = $129375
face value = 2.25 , charges are 15% more for smokers
⇒ Charges = 15% of 250000 = $37500
Total charge = Charge × face value
= 37500 × 2.25 = $84375
Hence, The option A. is correct that is Aaron is paying the smallest premium possible with company B
