three consecutive integers
the sum of the first two integers is 24 more than the third integer.
This means that the three integers are 25, 26 and 27.
Substitute the numbers for the variables
4+(-2)(4/5)
easier if you turn 4/5 into a decimal
4+(-2)(0.8)
multiply -2 and 0.8
4+(-1.6)
add
4-1.6
answer is 2.4
We have a
number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that

begins in -3 and closes in 8, that is,

<em>takes values from -3 to 8</em>. In a mathematical language this is given by
the following statement:
</span>
![x \in [-3,8]](https://tex.z-dn.net/?f=x%20%5Cin%20%5B-3%2C8%5D)

The base of the middle triangle is 3 and the base of the larger one is 6, so the larger triangle is twice the size of the middle one.
Multiply the height of the middle one by 2 to get the height of the larger one, which is labeled n.
n = 5 x 2 = 10
