7 0

Answer:

b. 21

Step-by-step explanation:

The first five mutiples of 7 are: 7, 14, 21, 28, 35. You can get these by multiplying 7 to any integer.

7x1 = 7
7x2 = 14
7x3 = 21
7x4 = 28
7x5 = 35

In order to get the average of these numbers, you have to add them and divide the sum to the total number of multiples.

Let's add first.

7+14+21+28+35 = 105

Let's divided 105 by 5, which is the number of the multiples of 7.

105÷5 = 21

The answer is 21.

Anna35 [415]

Answer: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, 11 + 21 > 16, 11 + 16 > 21, and 16 + 21 > 11, you can form a triangle with side lengths 11 mm, 21 mm, and 16 mm.

Answer:

$x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}$

Step-by-step explanation:

$x^{3} -5x^{2} -6x +8 \frac{-2}{x + 3}$

x + 3 / $x^{4} - 2x^{3}-21x^{2} -10x +22$

-( $x^{4} + 3x^{3}$ )

- $5x^{3} -21x^{2} -10x +22$

-( $-5x^{3} -15x^{2}$ )

$-6x^{2} -10x +22$

-( $-6x^{2} -18x$ )

8x +22

-(8x + 24)

$\frac{-2}{x + 3}$
