Answer:


Step-by-step explanation:

(1-2z)(1+2z) = 1-4z^2

you don't have a correct choice  given the problem


is it possible there is a negative out front of the problem


- (1-2z)(1+2z)  = -(1-4z^2)  = 4z^2 -1

Otherwise, send an email to your instructor

I need help on this. How do you find the area of this shape?
dimaraw [331]
To find the area of this shape you must first find the area of the rectangle 8 x 13 = 104. Once you find the area of the rectangle you must then find the area of the triangle which is base x height divided by 2. So to find the base of the triangle you must add the 4s on the bottom and subtract it by 13. So 13-8=5 so the base of the triangle is 5, the height is 6 and 5x6 is 30. You then divide it by 2 so you get 15. Now you take the area of the rectangle,104 and subtract it by the area of the triangle, 15. The answer is 89. I hope this helps.

For which k are the roots of k(x2+1)=x2+3x–3 real and distinct?
Ugo [173]

Answer:

The solution for k is the interval (-3.5,1.5)

Step-by-step explanation:

we have

k(x^{2}+1)=x^{2}+3x-3

kx^{2}+k=x^{2}+3x-3

x^{2}-kx^{2}+3x-3-k=0

}[1-k]x^{2}+3x-(3+k)=0

we know that

If the discriminant is greater than zero . then the quadratic equation has two real and distinct solutions

The discriminant is equal to

D=b^{2}-4ac

In this problem we have

a=(1-k)

b=3

c=-(3+k)

substitute

D=3^{2}-4(1-k)(-3-k)\\ \\D=9-4(-3-k+3k+k^{2})\\ \\D=9+12+4k-12k-4k^{2}\\ \\D=21-8k-4k^{2}

so

21-8k-4k^{2} > 0

solve the quadratic equation by graphing

The solution for k is the interval (-3.5,1.5)

see the attached figure
