Answer:

D. 11

Step-by-step explanation:

Midsegment theorem:

The length of the midsegment of a triangle is half the length of it's third side.

In this question:

Third side: 3x - 5

Midsegment: 14m

So

\frac{3x - 5}{2} = 14

3x - 5 = 28

3x = 33

x = \frac{33}{3}

x = 11

The correct answer is given by option D.

Find lim x->2 for f(x)=
TiliK225 [7]

LHL in not equal to RHL , Therefore the limit does not exists , Option D is the answer.(none)

<h3>What is the limit of a function ?</h3>

The limit of a function at a certain point is the value that the function approaches as the argument of the function approaches the same point.

It is given that

lim x->2 for f(x)

\lim_{x \rightarrow 2^-}f(x) = \lim_{x\rightarrow 2^+}f(x)

f(x) = 2x+1 x ≤2

f(x)= x² , x >2

When both the function tends to 2

Left Hand Limit

f(x) = 2 *2 +1

f(x) = 5

Right Hand Limit

f(x) = x² ,

f(x) = 4

LHL in not equal to RHL , Therefore the limit does not exists.

Find a polynomial, which, when added to the polynomial 5x^2–3x–9, is equivalent to <br><br> x^2-5x+6
alexandr1967 [171]
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9

wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2

then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x

-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15

Geometry please help! <br> 7. Kite<br> x = _ y = 146
Rasek [7]
The angles of a kite adds up to 360 so 146 + 146 + 47 which equals 339. 360 - 339 equals 21 so x = 21 degrees. hope that helps!

-5n = -6n – 4<br> Can't figure out this equation need help on solving for n
IrinaVladis [17]
Remember you can do anything to an equatino as long as you do it to both sides
add 6n to both sides
6n-5n=6n-6n-4
1n=0n-4
n=-4

Given that £1 = $1.62<br> b)<br> a) How much is £650 in $?<br> b) How much is $405 in £?
arsen [322]

Answer:

A) £650 = $1053

B) $405 = £250

Step-by-step explanation:

For a) Since £1 is equal to $1.62 you would just do £650 times 1.62 to get $1053

For b) Since £1 is equal to $1.62 you would do $405 divided by 1.62 to get £250
