<span>(a+b)(c+d)=ab+ad+bc+bd
(5k-4)(4k-5)=20k^2+-25k-16k+20=20k^2-41k+20
Hope this helps!</span>

To solve the problem shown bove you must apply the proccedure shown below:
1. You have that:
2a-1<<span>7−1.2a
2a+1.2a<7+1
3.2a<8
a<8/3.2
a<2.5
2. Therefore, f</span><span>or what values of a is the value of the binomial 2a−1 smaller than the value of the binomial 7−1.2a?
</span><span>
As you can see above, the answer for this question is:
All the values of a between -</span>∞ and 2.5<span>
</span>
