Answer:

C. 2(k +2)(k +5)(k +1)

Step-by-step explanation:

The LCM will be the product of unique factors.

$(k^2 + 3k + 2)=(k+1)(k+2)\\(2k^2 + 14k + 20)=2(k+2)(k+5)$

The unique factors are 2, (k+1), (k+2), (k+5), so the LCM is their product:

2(k+1)(k+2)(k+5) . . . . matches choice C

What is the value of x? Enter your answer in the box. x = A triangle with midsegment parallel to the base. the left side is labe

inessss [21]

A segment is only a "midsegment" if it connects midpoints. When labels above and below are 9 and 72, it is clearly not a midsegment. However, because it is parallel to the base, segments above and below on one side are proportional to those in similar positions on the other side.

72/9 = 56/(3x -20)

We can multiply by (3x -20)/8 to get

3x -20 = 7
3x = 27
x = 9

What is between 3/8 and 7/16

Anit [1.1K]

Answer:

13/32 is one of the numbers between 3/8 and 7/16

Step-by-step explanation:

The set of rational numbers is very dense.

For any given two rational numbers, we can find infinitely many rational numbers between them.

Similarly, there are many rational numbers between 3/8 and 7/16.

One of them is the number in the middle.

To find it add and divide the result by 2.

$\frac{ \frac{3}{8} + \frac{7}{16} }{2}$

$\frac{ \frac{6}{16} + \frac{7}{16} }{2}$

$\frac{ \frac{13}{16} }{2}$

$\frac{13}{32}$

600 is how many times as much as 20?

Montano1993 [528]

The value 600 is 30 times as much as 20

<h3>Ratio and proportion</h3>

Ratio are written in terms of fractions. The expression 600 is how many times as much as 20 can be written as;

600 = x *20

where x is the required value or factor

20x = 600

Divide both sides by 20

20x/20 = 600/20

x = 30

Hence the value 600 is 30 times as much as 20
