Answer:
Slope = 5
Step-by-step explanation:
y = mx + b
m = slope
Slope = 5
Let S, M, L represent the shortest, mid-length, and longest sides, respectively. You are given three bits of information.
.. S +M +L = 14.5 cm
.. L = 2S
.. L = 6.2 cm
You can use an equation something like this to find the middle-length side.
.. (6.2 cm)/2 +M +6.2 cm = 14.5 cm
.. M +9.3 cm = 14.5 cm . . . . . . . . . . . . . constant terms collected
.. M = 5.2 cm . . . . . . . . . . . . . . . . . . . . . subtract 9.3 cm
Now, you know the side lengths are 3.1 cm, 5.2 cm, 6.2 cm.

You have not offered any choices for "which equation," so take your pick of those used here.
The answer to this problem is simple to find the answer we must see the keywords in the sentence on of is how many which can mean addition/multiplication so here the problem is increasing in a rate of 3 3x1=3
3x2=6 3x3=9 and so on 3x7=21 your answer is 21
You simplify it by doing distributive property like this
(4+2i)(3-i) =12-4i+6i-2i2
now add common like numbers
12+2i-2i2
Now on the i that is squared change the i to a -1 and get this
12+2i+2
Now again add common like numbers and get
14+2i that would be your answer
hope this helped
