All you have to so is divide 1968 by 4.
1968 ÷ 4 = 496.5 = 1/4
Now multiply 496.5 by 3 = 1, 489.5 = 3/4
I hope this helps! :_
We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>
72 degrees
(well it says answers need to be 20 words long.. So I wrote this)

so, no breaks on the denominator thus, the LCD will be all three then.
Answer:
f(3) = 7
Step-by-step explanation:
Substitute x = 3 into f(x) , that is
f(3) = 4(3) - 5 = 12 - 5 = 7
