Step-by-step explanation:

\tan \angle A =  \frac{3}{6}  \\  \\  \therefore \:  \tan \angle A =  0.5 \\  \\ \therefore \:  \angle A =  { \tan}^{ - 1}  0.5 \\  \\  \therefore \:  \angle A =  { \tan}^{ - 1}  0.5 \\  \\ \therefore \:  \angle A =  { \tan}^{ - 1}  tan(26.565051177 \degree) \\  \\ \therefore \:  \angle A  = 26.57 \degree

Factor completely. -2k - k3^ - 3k^2
wlad13 [49]

Answer:

-k(k+1)(k+2)

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

-2k-k^3-3k^2 = -k(2+k^2+3k)

We will rearrange and factor the trinomial.

-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)

write two division problems related to the multiplication problem below. 8×(-2)=-16
Mrac [35]

We can write two division problems related the given equation as follows.

Division problem one :

Here 8 is in multiplication with -2 on the left side.

so when we bring this 8 on the right side, we will have to apply opposite operation of multiplication which is division.

so dividing (-16) by 8 on the right side, we have:

-2=\frac{-16}{8}

Division problem two :

Here -2 is in multiplication with 8 on the left side.

so when we bring this (-2) on the right side, we will have to apply opposite operation of multiplication which is division.

so dividing (-16) by (-2) on the right side, we have:

8=\frac{-16}{-2}
