i believe that it’s a but i don’t want to get it wrong can someone help me (no wrong answers pleaseee)
VARVARA [1.3K]

Answer:

B

Step-by-step explanation:

For the divisor on the left of the division symbol, the -3 symbolizes that the -3 is a root. This means that when we plug -3 into our divisor, the answer is 0. Therefore, as x+3=0 when x=-3, the divisor is x+3.

Next, for the dividend, we can start on the left with no x multiplied to it and then add one degree of x for each value to the left. This results in

6 + -4 * x¹ + 4 * x² + 2 *x³

= 2x³ +4x² -4x+6

In ΔKLM, m = 18 inches, ∠M=124° and ∠K=29°. Find the length of k, to the nearest 10th of an inch
Anastaziya [24]

Answer:

10.5

Step-by-step explanation:

sin29

k

​

=

sin124

18

​

Plug in. Opposite sides go together.

k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5

k=

sin124

18sin29

​

≈10.526≈10.5

I WILL MAKE YOU THE BRAINLIEST EASY QUESTION
trapecia [35]

Answer:

You can convert the denominator of each to 16 to compare each fraction. The wrenches should go in order from least to greatest: 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4. Place on number line between 0 and 1. The number line shows values that are least on the left to the greatest values to the right.

Step-by-step explanation:

You can find a common denominator to compare all the fractions. The common denominator should be the LCM or lowest common multiple of 2, 4, 8, and 16. Since all can multiply to 16, this is the common denominator.

1/2 = 8/16

3/4 = 12/16

3/8 = 6/16

5/8 = 10/16

5/16

7/16

9/16

11/16

Now place in order according to the numerator value:

5/16, 6/16, 7/16, 8/16, 9/16, 10/16, 11/16, and 12/16. We'll now write the list using the original fractions instead of their conversions.

5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, and 3/4

Place these on the number line in order between 0 and 1.
