Answer:
zeros
x=0
x=4 with multiplicity 2
Step-by-step explanation:
We need to solve x^3-8x^2+16x=0
Notice each term has a factor of x in common in x^3-8x^2+16x so we can factor it as x(x^2-8x+16)
Now x^2-8x+16 is a quadratic where a=1... We can see if it is factorable by looking for two numbers that multiply to be 16 and add up to be -8 which is -4 and -4
So you have x^3-8x^2+16x=0 is equivalent to x(x-4)(x-4)=0 (this one is in factored form).
x=0
x=4 (multiplicity 2 since you had the factor that is came from occurring twice)
Answer:
4*2
Step-by-step explanation:
I would say 4 is the length and 2 is the width
(4*2)+(2*2)=12
Answer:
hint for the first part
Step-by-step explanation:
3.50+(1.25*6)=
Distribute the outside terms through the terms inside the parenthesis.
2(x - 4) + 7 = 3
2x - 8 + 7 = 3
Combine like terms.
2x - 1 = 3
Add 1 to both sides of the equation.
2x = 4
Divide both sides by 2.
x = 2
You can look at those dots, for example, you see (2,8) and (2,2) then look at y and the difference is 6. so if you see it like that, (2,8) and (5,8) is 3, (5,8) and (5,4) would be 4, (5,4) and (8,4) would be 3, (8,4) and (8,2) would be 2, and lastly (2,2) and (8,2) is 6
Now you add all of them up which will be 6+3+4+3+2+6 = 24
so the perimeter of this figure is 24<span />
