Answer:
Step-by-step explanation:
1. 6(a +2b +3c)
2. (6 x 1a) + (6 x 2b) + (6 x 3c)
*Note that I put a 1 in front of the a. I did this because a means there is 1a so by putting the 1 there, it makes it easier to see that 6 x 1= 6, therefore we now have 6a.
3. Answer:
(6a) + (12b) + (18c)
* If you ever have an equation like this that has two of the same letters such as if 12b was 12a, then you could combine those since they are like terms. But since we have three different letters, this is the most simplified answer. Hope this helps!!(: If you have any questions just let me know!
Answer:
Length = 34
Step-by-step explanation:
Perimeter of rectangle = a+a+b+b = 2(a+b)
Let a = length = 2b - 4
Let b = width
Therefore
(2b-4) + (2b-4) + b + b = 106 cm
Bracket off
2b-4+2b-4+b+b = 106cm
Collect like terms
2b+2b+b+b-4-4 = 106cm
6b-8 = 106
6b = 106+8
6b = 114
b = 114÷6
b = 19
To get a
2b - 4
2(19) - 4
38-4
= 34
