$${{\mathtt{0}}}^{{\mathtt{2}}} = {\mathtt{0}}$$

This is because you are multiplying 0 by itself, and any number multiplied by 0 equals 0.

error i think idk or enfinity thats whut i keep geting...

2.5² x 3.5²  =  6.25 x 12.25  =  76.5625

Calculators are useful!

To subtract means to add the opposite; so subracting a negative is the same as adding a positive:

3 - -3  =  3 + 3  = 6

i cant continue to write my proof.Ok triangle ABC is congruent to triangle A'B'C'. Segment AD bisects angle BAC

and segment A'D' bisects angle B'A'C'. Proof segment AD is congruent to A'D'.

 Because triangle ABC is congruent to triangle A'B'C' (given)

so angle BAC = angle B'A'C'  angle BCA = angle B'C'A'$$\Rightarrow$$ angle DCA = angle D'C'A' (corresponding angles of two congruent triangles are equal)

and   segment AC = segment A'C' (corresponding sides of two congruent triangles are equal)

because AD bisects angle BAC (given)

so angle BAD = angle CAD =1/2 angle BAC (angle bisect theorem)

same, angle B'A'D' = angle  C'A'D' =1/2 angle B'A'C'

because angle BAC = angle B'A'C'  (proved)

 1/2 angle BAC =1/2 angle B'A'C  $$\Rightarrow$$ angle DAC =angle D'A'C'

In the triangle DCA and triangle D‘C'A'

angle DAC =angle D'A'C'

segment AC = segment A'C'

angle DCA = angle D'C'A' 

so triangle DCA congruent to  triangle D‘C'A' (ASA) (angle -side-angle )

so segment AD is congruent to segment A'D' (corresponding sides of two congruent triangles are equal)I 

i wish that work. And left side the image have something wrong. i am really sorry. Thank you!

3x - 14 + 2(x - 9)  =  2x - 2

Use the distributive property:

3x - 14 + 2x - 18  =  2x - 2

Simplify:

5x - 32  =  2x - 2

Subtract 2x from both sides:

3x - 32  =  -2

Add 32 to both sides:

3x  =  30

Divide both sides by 3:

x  =  10

If each '?' represents a different number or variable, there are two many numbers/variables to determine a single nanswer.

The x-value of the vertex will be half-ways between the two zeroes. Half-ways between x = 10 and x = 34         is x = 22; so the vertex is the point (22, 24).

An equation of a parabola is:  y - k  =  a(x - h)²  where the vertex is (h, k) = (22, 24).

--->   y - 24  =  a(x - 22)²       Since a point on the graph is (10, 0), replaceng x with 10 and y with 0:

--->   0 - 24  =  a(10 - 22)² 

--->   -24  =  a(-12)² 

--->   -24  =  144a

--->   a  =  =1/6

Equaiton is:  y - 24  =  (-1/6)(x - 22)² 

20x+24=12x-3        add 3 to both sides

20x + 27 = 12x       subtract 20x from both sides

27 = -8x                 divide both sides by -8

-27 / 8  = x

Okay Thanks! CPhill you help people a lot!

20x + 24  =  12x - 3

Get all the variables to one side; subtract 12x from both sides:

--->     8x + 24  =  -3

Get all the number terms to the other side; subtract 24 from both sides:

--->     8x  =  -27

Divide both sids by 8:

--->     x  =  -27/8

1. Add 3 to both sides    (we want all the "non x" terms on one side and all the "x's" on the other)

We have that (a/b)^-n = (b/a)ⁿ

So

(10 /9)^-2  = (9 /10)² = 81 / 100

Thanks!!!! 

Ok.....from the beginning, we would have

$10P + $6B ≤ $50     where P is the number of papayas and B is the number of bananas

f(x) = cx -1.28   so....if x = 6, f(x) = 23 and we have

23 = c(6) - 1.28     add 1.28 to each side

24.28 = c(6)      divide both sides by 6

c = about 4.046

Ok thanks phil. I just made my account after that question, but what would the inequality be from the very beginning? without doing anything.

Do you get it?

Good job.......!!!!

She has $30 to spend on bananas

So  the  max number she can buy is representsed by

6B ≤ 30    divide by 6 on each side

B ≤  5       where B is the number of bananas  (man, that's some expensive fruit!!)

It is -4 so the answer is 2m -4!!!!!!!!!

3 1/2 - 1 1/5 is pretty easy to figure out once you get the hang of it! First you need to get common denominators... What is the most common factor between 2 and 5 that would be..... 10! Here is an example of what to do

2x5=10 5x2=10 now do that to both sides so you end up with fractions like this:

3 5/10 - 1 2/10

Then you just subtract! If you need more help just go to MathisFun.com and type in subtracting Fractions!
