X2 - 8x + 15 = 0
(x - 3)(x - 5) = 0
critical points are at 3 and 5
If there is a negative tile and a positive tile, it creates a zero pair.
Like terms can occur with the same variables (except for terms with exponents)
Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
Answer:
No, they are not the same.
Step-by-step explanation:
Lets say the price is 100 dollars. Lets start with the 25 and then 10 percent off. Since its 25% off we need to multiple the 100 dollar price by .75.
100*.75=75
Now that we have the 75 dollar price, we need to take off the 10%. We need to multiply the current price of 75 by .9
75*.9=67.5
The price after these 2 discounts is $67.50
Now lets do the 35% off right away. Since is 35% off we need to multiple our right of 100 by .65.
100*.65=65
The price after the 35% off is $65
So no, they are not the same.
