Answer:
Step-by-step explanation:
2x*2x=4x^2
2x*3=6x
Keep in mind 4x^2-6x
then next part:
3*2x=6x
3*3=9
6x-9
So totally
(4x^2-6x)-(6x-9)
Minus and minus is equal to +
(4x^2-12x+9)+2=45
4x^2-12x+11=45
-11 on both sides
4x^2-12x=34
X= -17/-2
Answer:
Associative property of addition
Step-by-step explanation:
To “associate” means to connect or join with something. According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped.
Ƒ(x)=3x^3+12x^2+3x-18 = 3(x-1)(x+3)(x+2)
Answer:
16.75 meters
Step-by-step explanation:
This problem is a plug in problem.
H = 0.20x + 12.75
we plug in 20 for x which gives us
(0.20 * 20) + 12.75
which equals
4 + 12.75
giving us
16.75 meters
Since, each row has one more log than the row above it
so, this is arithematic sequence
We are given that
First row is
so,
Last row is
so,
Each row has one more log than the row above it
so,
now, we can find number of rows
we can plug values
we can solve for n
now, we can find total number of logs
now, we can plug values
So,
Number of logs in the pile are 119........Answer
