The standard form of a quadratic equation is
,
where 
, 
, and 
are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is
Since 
is on the right side of the equation, we subtract that from both sides. The resulting equation is
Looking at the standard form equation , we can see that
Answer: 82.88
Step-by-step explanation:
BxHxW
7.4 x 3.2 = xxx
7.4 x 8 = xxx
So, what you'll do is combine both of the sums, and you will get 82.88
Answer:
Step-by-step explanation:
The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.
Answer:
x = (-7,7)
Step-by-step explanation:
1.add 5 on both side
2.divide each side of the equation by 2
3.take the square root of each side of the equation to solve for x
