a) (x+6)^2-25
b) (-6, -25)
Step-by-step explanation:
Perfect square trinomial! If you have 12x, divide by two and get 6, so we have (x+6)^2+q. Then solve for q. You get q as -25.
For b, we just take the vertex from vertex form. We get x+6=0 so x=-6, and q = -25, so the answer is (-6, -25).

Answer:
Step-by-step explanation:
y=(2x²+x)³+(x-1)/(1-x)
=(2x²+x)³+(x-1)/-(x-1)
=(2x²+x)³-1
dy/dx=3(2x²+x)(4x+1)-0
=3x(2x+1)(4x+1)
Answer: 4
Step-by-step explanation:
The degree is the highest exponent , in which in this problem it is 4. The 3x counts as an exponent of 1 because the variable x is 1, and the 2 counts as an exponent of zero. Which means the degree is 4.
The correct statement that represents the expression is:
- An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m
Given the expression 56 + (-56).
- We can see that this is an inverse rule where a value and its negative are added together.
Let us assume the values are distance covered by an object.
The correct statement that represents the expression is:
- An object moves towards the east (positive direction )at a distance of 56m and west (negative direction) at the same distance, the total displacement of the object is 0m
This show that 56 + (-56) = 56 - 56 = 0

Answer:
Step-by-step explanation:
Given: Trey's test score average decreased by 14 points this semester.
To find: a signed number to represent this change in average.
Solution:
The decrease can be denoted by minus 
sign and increase can be denoted by plus 
sign.
So, a signed number to represent the change in test score average is
