You just needed to do is 25% and then times it by 21 you should get 5.25
Answer:
true
Step-by-step explanation:
Answer: (18/5) * 11
Step-by-step explanation:
In equations of proportion, to proceed, we need to determine the constant of proportion, let's denote as "k"
Since y ~ x
Means y=kx.
To determine the value of k, we input initial values of y and x.
Initial value of y = 18
Initial value of x = 5
The equation becomes :
18 = 5k
k = 18/5.
Now, If given the value of x as 11,to determine the value of y we go back to the equation.
y= kx
y = 18/5 * 11.
The answer to part A is 1,852.50
3x^3+12x^2+3x
The GCF would be 3x, you can factor out a 3x
3x(x^2+4x+3)
You can further factor the problem...
3x(x+3)(x+1)
Another equivalent form can be made if you simply distribute 3x into x+3
(3x^2+9x)(x+1)
