<span>8x^2 - 2x - 1 = 0
(2x - 1)(4x + 1) = 0
2x - 1 = 0; x = 1/2
4x + 1 = 0;x = -1/4

Answer:
h= 0.25c +4
Step-by-step explanation:
➀ Define variables
Assuming that you are asking for the equation representing the height of the stack, let's start by letting the height of the stack be h inches and the number of cups be c.
➁ Find the increase in height with every additional cup
If an additional cup is stacked on the first cup, the height increment is 0.25 inches. When 2 cups are added, the height increment is 2(0.25)= 0.5 inches. Thus the expression for the increase in height is 0.25c, where c is the number of cups as we have already defined in step 1.
➂ Find the total height of the stack
Since the height of the first cup remains constant at 4 inches tall, the total height of the stack can be represented by the equation:
h= 0.25c +4
1- distributive property
4- identity property
8- commutative property
Answer:
3+2 = 22 +30= 59 1/2
(x + c)2 = d or (x – c)2 = d. = (c * d)(x) = 4x^3 + 18x^2 - 10x
X=1+2

sorry if wrong was every confused
Answer:
D
Step-by-step explanation:
Just look for a pattern.
distance from -3 to 6 is 9
distance from 6 to 15 is 9
distance from 15 to 24 is 9
They're just adding 9 each time
24 plus 9 is 33
33 plus 9 is 42
42 plus 9 is 51
