Answer:
x = 1
Step-by-step explanation:
Remember that the axis of symmetry is exactly halfway between the x-intercepts. Find the average of -3 and 5 to obtain this x-value: It is:
-3 + 5
x - intercept = ------------ = x = 1

Answer:
No, she's incorrect. You cannot split up something in parenthesis when it is being squared. By doing so she doesn't have a middle term. The correct equation is 25x^6 + 30x^3 + 9
Step-by-step explanation:
1. Square the first term.
(5x^3)^2 = 25x^6
2. Square the second term.
3^2 = 9
3. Multply the two terms together and multiply by two.
5x^3 × 3 = 15x^3
15x^3 × 2 = 30x^3
4. Add everything together.
25x^6 + 30x^3 + 9
I hope this helps!
Answer:
Step-by-step explanation:
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
4 in * 28 ft * 14 ft = 4 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(4*28*14)/(36*3*3)= 1955/324=
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
24-x/6=-5
I'm not sure if this is correct
