Answer:
-83, -82, and -81
Step-by-step explanation:
Step 1: Declare your variable
Let x represent the largest of the 3 consecutive integer
Integer 1: x
Integer 2: x + 1
Integer 3: x + 2
Step 2: Create an equation
(x) + (x + 1) + (x + 2) = -246
Step 3: Solve
x + x + 1 + x + 2 = -246
3x + 3 = -246
3x = -249
x = -83
FInd the other 2 numbers
Integer 1: -83
Integer 2: -82
Integer 3: -81
Step 4: Therefore Statement
Therefore the 3 consecutive numbers are -83, -82, and -81
Answer:
B.
Step-by-step explanation:
So will have two factors if one factor in the form
is given.
The other factor will also be in the form of .
So we have
:
Let's use foil.
First: x(cx)=cx^2
Outer: x(d)=dx
Inner: 1(cx)=cx
Last: 1(d)=d
---------------------Adding like terms:
cx^2+(d+c)x+d
We are comparing this to:
2x^2+ 5x+3
So we see that c=2 and d=3 where the other factor is cx+d=2x+3.
Also this works since c+d=5 (we know this because 2+3=5).
Answer:
Step-by-step explanation:
We are given that:
And:
And we want to find:
This is a recursive formula. So we can simply substitute in each value. For instance, a₂ will be:
Thus, a₃ will be:
Finally, a₄ will be:
