Question

The value of 13ab + 6a + 5 for a=2, b =(-1​

Answer 1

Answer:

28

Step-by-step explanation:

To do this problem, it is important to look at these variables as an integral part of the equation. (a) and (b) can actually be replaced in this equation when you are shown an equivalent form… so you can replace 1) a->6, and 2) b->5. In this equation, when you have characters next to one another, then they are most likely going to be multiplied. For example, 6q is 6 times q and 3(8) is 3 times 8.

With this problem, you can input the numbers like this:

3a+2b = 3(6)+2(5) or 18+10.

=28.

I hope this helps, and that you have a great day!
