Hello,
let x the first angle
5x the second
2/3 x the third
x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18
27+135+18=180
To solve for this, we need to find for the value of x
when the 1st derivative of the equation is equal to zero (or at the
extrema point).
So what we have to do first is to derive the given
equation:
f (x) = x^2 + 4 x – 31
Taking the first derivative f’ (x):
f’ (x) = 2 x + 4
Setting f’ (x) = 0 and find for x:
2 x + 4 = 0
x = - 2
Therefore the value of a is:
a = f (-2)
a = (-2)^2 + 4 (-2) – 31
a = 4 – 8 – 31
a = - 35
Answer:
C
Step-by-step explanation:
Answer:
6(8+3x)
Step-by-step explanation:
48+18x
We can factor out an 6 from each term in the expression
6(8+3x)
if we take 2100 to be the 100%, what is 273 off of it in percentage?
