The sum of four consecutive integers is - 18. What is the greatest of these
rjkz [21]

Answer:

-3

The problem:

The sum of four consecutive integers is - 18. What is the greatest of these

integers?

Step-by-step explanation:

If n is the first integer, then n+1 is the second integer, n+2 is the third integer, and n+3 is the fourth integer in consecutive order.

For example if n=8, we are saying n+1=9,n+2=10, and n+3=11, which I think you can see that 8,9,10,11 are consecutive.

So the sum is -18 which means:

n+(n+1)+(n+2)+(n+3)=-18

4n+6=-18

Subtract 6 on both sides:

4n=-18-6

Simplify:

4n=-24

Divide both sides by 4:

n=-6

If n=-6,

then:

n+1=-6+1=-5

n+2=-6+2=-4

n+3=-6+3=-3.

So the 4 consecutive integers whose sum is -18 is: -6,-5,-4, and -3.

The greatest of these integers is -3.

Factorize the following: <br>49x² - 25​
creativ13 [48]

Answer:

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.
