Answer:

The answer is option 1.

Step-by-step explanation:

You have to use Distributive Laws,

$a(b + c) = ab + ac$

So for this question :

$(6r - 1)( - 8r - 3)$

$= 6r( - 8r) + 6r( - 3) - 1( - 8r) - 1( - 3)$

$= - 48 {r}^{2} - 18r + 8r + 3$

$= - 48 {r}^{2} - 10r + 3$

Select the correct answer for each statement. (k+2, k+3 , k+4) or (k+10, k+12, k+14) will yield consecutive odd integers. (k+6,

Answer:

Step-by-step explanation:

one

The only really certain way of getting an odd integer is to do 2k + 1. Therefore the answer should be something like 2k+1, 2k+3, 2k + 5

The best I can do for the first one is to assume that k is odd and that the answer is k + 10, k+12, k+14, but I would ask your instructor if this is merely the best answer out of a poor lot or if the question really has no answer.

Two things should be noted.

1. k has to be odd.

2. The first choice has to give consecutive integers because what is added on is 2 3 and 4. Those numbers are consecutive.

Two

k+1, k+2, k+3. See point 2 above. k is a constant and any number. 1,2,3 are consecutive so the results are consecutive. Even if k < 0 the numbers will be consecutive.

k= - 10

k+1 = - 9

k+2 = -8

k+3 = - 7

These are consecutive.

Your first choice will give either consecutive odd or even numbers depending on what k is.

If k = even, then k+6, k+ 8, k+10 will all be even.

If k = odd then the givens will be odd.

How to solve 3+5 (c+3)=-17

BlackZzzverrR [31]

3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: $5(c + 3) = -17 - 3$
Second, simplify -17 - 3 to get -20. / Your problem should look like: $5(c + 3) = -20$
Third, divide both sides by 5. / Your problem should look like: $c + 3 = -\frac{20}{5}$
Fourth, simplify $\frac{20}{5}$ to 4. / Your problem should look like: $c + 3 = -4$
Fifth, subtract 3 from both sides. / Your problem should look like: $c = -4 - 3$
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: $c = -7$

Answer: c = -7
