29.99-20%= 23.99
25.00-10%= 22.50 so, Mr.chang got the better deal ( but not by much.)
Answer:
3x^4-18x^3+27x^2-12x
Step-by-step explanation:
Multiply the second paréntesis for each term of the first parentage
3x^2×(x^2-2x+1)-12x×(x^2-2x+1)
Multiply parentage by 3x^2
3x^4-6x^3+3x^2-12x×(x^2-2x+1)
Multiply the parentage by -12x
3x^4-6x^3+3x^2-12x^3+24x^2-12x
Group similar terms
3x^4-18x^3+27x^2-12x
Answer:
112
4 to the second power is 16, multiply by 7 get 112
Step-by-step explanation:
Answer:
It’s nonlinear because you can’t put x by itself
Step-by-step explanation:
Answer:
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)
Step-by-step explanation:
We have a function:
f(x)=(x+6)(x+6)
This function is also equal to f(x)=(x+6)^2
This is the square of the binomial. It has only one zero
f(x)=(x+6)^2 = 0
If we take square root we get:
√(x+6)^2 = 0
x+6 =0
x= -6
The only function that has only one zero at -6 is f(x) = (x + 6)(x + 6)....
