B. 55 seconds
The average equals the sum of all the numbers then divided by the amount of numbers added.
51+53+55+56+60=275
275/5=55 seconds
Answer:
Step-by-step explanation:
It usually works best for factoring to remove any common factors from the coefficients. Here, they are all even numbers, so have a common factor of 2. After taking that out, you have ...
2(4x² -4x -3)
To factor this, you are looking for factors of (4)(-3) that have a sum of -4.
-12 = 1(-12) = 2(-6) = 3(-4)
These pairs have sums of -11, -4, -1. So, we are interested in the factors 2 and -6. We can use those to rewrite the middle term, then factor by pairing.
= 2(4x² +2x -6x -3) = 2((2x(2x+1) -3(2x+1)) = 2(2x -3)(2x +1)
Of these, the factors that are on your list of choices are ...
Answer:
-2, -7 is the answer to the question
Answer:
-5x³ + 10x² = -5x²(x - 2)

Answer:
You are transposing so
and
Step-by-step explanation:
Basically in transposing, you use reverse operations to get rid off attached or unnecessary terms till you get what you want on one side of the equal sign
