Find the sum of the constants a, h, and k such that
ra1l [238]

Answer:

  3

Step-by-step explanation:

The value of "a" is the coefficient of x^2, so we know that is 2.

__

<u>Solve for h</u>

Now, we have ...

  2x^2 -8x +7 = 2(x -h)^2 +k

Expanding the right side gives us ...

  = 2(x^2 -2hx +h^2) +k

  = 2x^2 -4hx +2h^2 +k

Comparing x-terms, we see ...

  -4hx = -8x

  h = (-8x)/(-4x) = 2

__

<u>Solve for k</u>

Now, we're left with ...

  2h^2 +k = 7 = 2(2^2) +k = 8 +k

Subtracting 8 we find k to be ...

  k = 7 -8 = -1

__

And the sum of constants a, h, and k is ...

  a +h +k = 2 +2 -1 = 3

The sum of the constants is 3.

Which product is negative?
GaryK [48]

The product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.

<h3>How to Find the Product of Negative Numbers?</h3>

The rule when multiplying two negative numbers is that, the negative signs will cancel each other. That is, minus multiplied by minus will give as plus.

For example, -a × -b = ab

Also, "plus" multiplied by "minus" will also give as "minus. For example:

-a × b = -ab.

Using the above rule, let's find the product of the following:

−3 × 5 × (−6) × 4 = -15 × (-24)

−3 × 5 × (−6) × 4 = 360 [minus × minus = plus]

−7 × (−3) × (−9) × 0 = 0 [anything multiplied by 0 must result to 0]

−4 × (−6) × (−3) × (−5)

= 24 × 15

−4 × (−6) × (−3) × (−5)  = 360

−3 × 4 × (−2) × (−7)

= -12 × 14

−3 × 4 × (−2) × (−7) = -168

Therefore, the product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.
