The answers because you have to add all of them together 35
Remove the parentheses
x^3-9x^2+27x-27-x^3+3x^2-3x+1+7x^2=21x-28
x^2+24x-26=21x-28
x^2+24x-26-21x+28=0
x^2+3x+2=0
factor the expression
(x+2)(x+1)=0
sooo x1=-2 x2=-1
Answer:
D
Step-by-step explanation:
For simpler calculation, we can round up the numbers.
Let's take 19.8 as 20, 9.8% as 10%, and 5.1% as 5%.
In 2014, 20 tons increased by 10%, so we would need to multiply 20 by 1.10 (this is 10% increase).
In 2015, we would need to increase the quantity "20(1.10)" by 5%, which means we would multiply that quantity by 1.05.
So, now we have 20(1.10)(1.05). This is equal to option D.
<u>Given</u>:
Given that we need to determine the value 0.15 of $2 dollars.
<u>Value</u>:
Let us determine the value of 0.15 of $2 dollars.
Value of 0.15 of $2 dollars can be determined by multiplying 0.15 by 2.
Thus, we have;
Multiplying the values, we get;
Thus, the value of 0.15 of $2 dollars is 0.3 dollars.
