answer
D 2
factor
factor the equation into (x + a) and (x + b) so that a + b = -2 and a * b = -8
the two numbers that meet these conditions are a = -4 and b = 2
find solutions
set both (x - 4) and (x + 2) equal to zero to find your solutions
x - 4 = 0
x = 4
x + 2 = 0
x = -2
add solutions
since the two solutions are x = 4 and x = -2, add them together to get your final answer
4 + (-2) = 2
Answer:
B. 1069 feet
Step-by-step explanation:
Adding the initial 125 feet to this, you get a total height of 1069 feet. Hope this helps!
We're given the Arithmetic Progression <em>-24, -4, 16, 36 ...</em> .
We know that a term in an AP is generally represented as:
where,
We need to find .
From the given progression, we have:
Using these in the formula,
Therefore, the 23rd term in the AP is -464.
Hope it helps. :)
