It's function use the equation with numbers they provided you if they did not use -2,-1,0,1,2 for input and use equation to find output.
Firstly setup an equation to find the perimeter:
3x + 4x + 5x = 54, this is because perimeter is equal to sum of all side lengths
Then combine like terms:
12x = 54
Now use the division property of equality by dividing both sides by 12:
x = 4.5
So then, you will substitute the value of x for each value of the side lengths:
3(4.5) = 13.5 for AB, 4(4.5) = 18 for BC, and 5(4.5) = 22.5 for AC.
Hope this helps and let me know if you have any more questions!
20 lbs. You multiply her weight with 15.5%. That is 0.155
Y = 3x - 1
The slope is 3, y goes up 3 for every increase in x
The intercept point of the Y axis is -1
Answer:
12
Step-by-step explanation:
a^2 + b^2 = c^2
(16)^2 + b^2 = (20) ^2
b^2 = 400 - 256
b = 
= 12
I hope im right!!
