Answer:
uv = 4
Step-by-step explanation:
(1+i√3)(1-i√3)
1²-(i√3)²
1-i²√3²
1-(-1)3
4
Let the amount that the boys sold be x, the amount that girls sold will be 3x. The total will be given by:
x+3x=180
4x=180
solving for x we get:
x=180/4
x=45
Thus, boys sold $45, the girls provided 45*3=$135
You can write the equation using conventional symbols as
3x^2 - 2x - 5 = 0
You can recognize that the middle coefficient is equal to the sum of the other two, so those two coefficients can be used to factor the equation.
(1/3)(3x +3)(3x -5) = 0 . . . . . put the coefficients in the form (1/a)(ax + ...)(ax + ...) (x+1)(3x-5) = 0 . . . . . simplify
The solutions are the values of x that make one or the other of the factors equal to zero.
x = -1
x = 5/3
Step 1. Find the Greatest Common Factor (GCF)
GCF = 3m^2
Step 2. Factor out the GCF <span>(Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3m^2(15m^2/3m^2 + -12m^3/3m^2)
Step 3. Simplify each term in parentheses
3m^2(5 - 4m)</span>
