(3x-4y)^2-(3x-4y)(3x+4y)

Mathematics
1 answer:

6 0

Answer:

-24xy + 32y^2

Step-by-step explanation:

Hello!

We can use the special binomial product formulas:

  • (a + b)^2 = a^2 + 2ab + b^2
  • (a + b)(a - b) = a^2 - b^2

<h3>Simplify</h3>
  • (3x - 4y)^2 - (3x - 4y)(3x + 4y)
  • (9x^2-24xy+16y^2) - (9x^2 - 16y^2)
  • 9x^2 - 9x^2 - 24xy + 16y^2 + 16y^2
  • -24xy + 32y^2

The simplified form is -24xy + 32y^2

Can someone give me the answer
Tasya [4]

Take the 4cm side and the 6cm side.

If you hook them together at one end, then there's no way they can reach the ends of the 11cm side.  The farthest they can reach is 10cm.

That's what choice-B says.

At 8:30 A.M.., Briana started filling a 2,800-gallon pond. At 10:30 A.M., she had filled 1,400 gallons. At what time will the po
Sati [7]

Answer:

12:30 pm

Step-by-step explanation:

8:30 am pond is empty

10:30 am pound is 1,400 gallons full

  time?    pound is 2,800 gallons full

from 8:30 to 10:30 are 2 hours so the rate of filling up is

             1,400 gallons in 2 hours

to have a whole pond filled we need another 2 hours because

in another 2 hours will have another 1,400 gallons so a pound full. 8:30 am + 2hours = 12:30 pm

8:30 am pond is empty

10:30 am pound is 1,400 gallons full

12:30 pm pound is 2,800 gallons full.

What is equivalent to 2x^2+9x+9
melamori03 [73]

(2x + 3) • (x + 3)

2x • x = 2x^2

2x • 3 = 6x

3 • x = 3x

3 • 3 = 9

6x and 3x combine to get 9x, which when all written out is equal to your original trinomial.

Change word phrase to expressions or equations<br><br> The sum of p and 45 less than 89
stellarik [79]

Answer:

p + 45 < 89

Step-by-step explanation:

The sum of something is the result of addition so you know that they are adding p and 45 together. They then state that p plus 45 must be less than 89. You can show that by using the less than symbol "<"

If you want to find all of the different values that P could equal then all you have to do is subtract 45 from both sides so the equation would be

p < 44

this means that p can equal anything less than 44 for this statement to be valid. Hope this helped!
