-5/6+x/6=1/x\Leftrightarrow x^2-5x-6=0

<span>\Delta=25+24=7^2 hence the answer is \frac{5\pm7}{2}=\left\lbrace-1,6\right\rbrace</span>

The question was incomplete. Below you will find the missing content.

In the figure below, BL, AM, and CK are medians of △ABC. If KC = 108 and OC = 2n + 10, then n=

The picture is attached below.

The value of n is 31.

The median is the line connecting the vertex and its midpoint on the opposite side of the triangle.

The intersection of all 3 medians of the triangle is called the centroid.

As we know centroid divides the median in the ratio of 2:1.

In the given picture,

Medians of triangle △ABC are AM, BL, and CK.

So the centroid of the triangle is O.

Given that KC= 108

As the centroid O divides the line KC in 2:1.

Let OC=2x

KO= X

As KC= KO+OC

⇒ 108= x+2x

⇒ 3x=108

⇒ x=108/3

⇒ x=36

Then OC= 2x= 2*36= 72

As given in the question OC= 2n+10

putting the value of OC in above equation

⇒ 72= 2n+10

⇒ 2n= 72-10

⇒ 2n=62

⇒ n=62/2

⇒n=31

Therefore the value of n is 31.

Find the limit , picture provided
V125BC [204]

Answer:

d. does not exist

Step-by-step explanation:

The given limits are;

\lim_{x \to 4} f(x) =5, \lim_{x \to 4} g(x) =0 and \lim_{x \to 4} h(x) =-2

We want to find

\lim_{x \to 4} \frac{f}{g}(x)= \lim_{x \to 4} \frac{f(x)}{g(x)}

By the properties of limits, we have;

\lim_{x \to 4} \frac{f}{g}(x)= \frac{\lim_{x \to 4} f(x)}{\lim_{x \to 4} g(x)}

This gives us;

\lim_{x \to 4} \frac{f}{g}(x)= \frac{5}{0}

Division by zero is not possible. Therefore the limit does not exist.

A gardener uses 20 gallons of water each week on his 8-foot by 10-foot vegetable garden. He plans to enlarge his
MatroZZZ [7]

Answer:

60 gallons

Step-by-step explanation:

so he enlarged it by three so it would be 24by30

because of that, you have to multiply 20g by 3 also

that gives you 60 gallons

Please help me on this math question?
Whitepunk [10]
M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30

n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found

t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98

use the earlier reasoning to fine the other answers of

p=71°
q=39°

use the angle degrees formula to get Pentagon's maximum angles then use earlier resources

the final answers u should be able to figure out from there and u will never learn unless you do some yourself
