Simplify (x + 5)2 using the square of a binomial formula.
Olegator [25]

Answer:

x^2 + 10x + 25

Step-by-step explanation:

Hello!

Formula: (a +b)^2 = a^2 + 2ab + b^2

  • a = x
  • b = 5

Plug it into the formula and simplify.

<h3>Simplify</h3>
  • (a +b)^2 = a^2 + 2ab + b^2
  • (x +5)^2 = x^2 + 2(x)(5) + 5^2
  • (x +5)^2 = x^2 + 10x + 25

The answer is the first option: x^2 + 10x + 25.

All of them!!!! Thanks for the help!!!!

Okay so the formula is y2-y1/ x2-x1

(X,Y) for example (2,7). That means 2=X and 7=Y. So I’ll do your first problem and you do the rest. (0,0) (3,3) remember y2-y1 over x2-x1. So 3-0=3 and 3-0 =3 so slope is 3/3. Simplified 1

What is the value of x in the equation 7(x − 2) = 5(x + 4)?
Zielflug [23.3K]

Answer: x= 17 I hope that helps you understand it Goodbye!

Step-by-step explanation:  

7(x-2)=5(x+4) So the first step is to Distribute meaning Multiply so 7(x-2 ) that would give you -14 that where I got that from and I just did 5(x+4)= 20 and bring the x down

1. 7x-14=5x+20 So, I just do the opposite of subtracting which is adding so, I'm going to add 14 to both sides

2. 7x=5x+20+14 = 5x+34

3. 7x= 5x+34 So, I'm going to do the opposite of adding now which is subtracting meaning I'm just going to subtract 5x from both sides

4. 7x-5x=34 So then I do 7x-5x=2x

5. 2x= 34 so. I just Divide 2 from both sides x=34/2= 17

So, your answer would be x=17 and yes you got to put the variable for your answer to be right you can't just put 17 it got to be x= 17 and variable is just letters in the equation don't let it confused you but that would be your answer x=17 And can you make me Brainliest Please
